DESCRIPTION

Amplifier/Receiver Manufacturer:

Model:

 AO-28

Description:

This is a Premium tube set for your Hammond AO-28 preamplifier used in the B-3, C-3, A-100 series, D-100 series, and the RT-3 organs.

Note for A-100, A-101, A-102, A-105, A-122 and A-143 organ owners:

If you have the A-100 (or other A-1xx models)  you may need additional tubes for the AO-39 power amplifier  or the reverb amplifier (either an AO-35 or AO-44 depending upon the organ configuration you have) which are also present in your organ.  The additional tubes are available as individual tube sets under the AO-39, AO-35 or AO-44 item descriptions in my eBay store.  Or to save some money you can buy all the tube sets for your A-100 organ as one complete set.  There are two complete sets for the A-100 series, one using the AO-35 reverb amplifier and the other using the AO-44 reverb amplifier.  Check your organ configuration to determine which reverb amplifier you have so you can order the correct set.

Note D-100, D-152 (Walnut), D-155 (Oak) organ owners:

If you have a D-100 organ (or other models), you may need additional tubes for the AO-33 power amplifier (which is also used in the PR-40 tone cabinet and technically known as the AO-33-1 or AO-33-5) used in your organ.  These tubes are available as an individual set under the PR-40/QR-40 tone cabinet auction in my eBay store or to save some money I also offer the complete tube set for the D-100 which includes both the AO-28 preamplifier and the AO-33-1 power amplifier. 

Note for RT-3 organ owners:

If you have the RT-3 organ you may also need additional tubes for the pedal solo unit that is in your organ.  I sell these tubes as a separate auction or you can save some money and buy the complete RT-3 set including the AO-28 amplifier in this auction and the pedal solo unit tubes.  See the Hammond RT-3 Complete Tube Set auction in my eBay store.

TESTIMONIALS

These tubes really work well!  Here is an email I recently got from a satisfied user:

"Hey, Robert!  Just wanted you to know that the tubes arrived, safe and sound, and talk about SOUND, the amp is literally twice as loud as before. The reverb is much better, although still not as strong as the amp I had stolen a year ago. Still, it's much better, and I thank you!

Played on stage Saturday night with it, and it was wonderful. Also, it's nice to have a complete backup set of tubes...it's a luxury I've never had in the 30 years I've been at this. Did a medley of "16 Tons" and "Hit the Road, Jack" in your honor.

Thanks for coming to my rescue. I only wish I could give you some sterling feedback...but not to worry, no good deed ever goes unrewarded!

Enjoy the blues...and your life in general! I'll be saving your address, so I can get ahold of ya if I need MORE tubes.

And Another Satisfied customer:

Just wanna say thanks.  After a half hour my amp warmed to a sound quality I’ve never had.  If you want to remind me in a year or two just in case I lose your info, that would be awesome. (Bedrock 1600)

From a Mesa Boogie customer:

Sorry I didn't get a chance to leave feedback sooner. The tubes came just as I was leaving for my summer vacation, literally, so I took them inside & left.

When I got home last night I got your message. I'm glad you wrote or I may have forgot about them. I just installed them, along with a new 3 amp sb fuse. Very nice!!! Make sure to check out your feedback, & when it's time to do my other amps, I'll look you up for sure. Great parts!!! Thanks again, (Mesa Boogie Mk-II 100 Reverb)
Greg.

PREMIUM TUBE SETS

PREMIUM TUBE SETS

We search the world over for vacuum tubes sets which we classify as PREMIUM.  They are value-priced (they don’t cost a small fortune) and make you and your amp sound great.

We choose many tubes from the 1940’s to the present.  Some tubes may have been hidden away for years in old warehouses, military bunkers, storage sheds or grandpa’s attic.  They come from Russia, Europe, Asia, and the good ole USA.  Recent great finds include Russian military (1960’s to 1980’s usually including 6V6/6N6C, 6L6GC/5881 equivalents, and 6BQ5/El84/6P14P equivalents, etc).  When they get into our tube lab, they are quality tested on Hickok 539B or 580 tube testers for gain, life test, shorts and physical appearance.  MATCHED TUBE SETS are matched first for manufacturer (tube code, not label) and then for gain/current draw.

We often get tubes that are decades old it and it is hard to determine if they are New in the Box (NIB), New Old Stock (NOS), bulk lots sold without boxes, or replacement tubes with great life still left in them.  Our extensive experience and comprehensive testing means we throw out a lot of old and new tubes if they test below minimum “NEW” reading on our calibrated tube testers or they don’t pass the LIFE TEST.  You can be assured that all the tubes we sell are NIB/NOS or tested new or better according to manufacturer standards.  We don’t specify the brands sold in Premium Tube sets since we want to give you the BEST VALUE for the price. With over 5,000 satisfied customers on EBAY, our quality control, selection criteria and value pricing have proven results, so we are confident that you will be pleased with your purchase.  For customers who want specific tube brands, these are often available as individual or matching tube sets. Click on the “Individual Tube Sets” links to the left of this description for a great selection or ask us before you bid.

We arrange all the tubes we sell into several classes to make it easier to find what you need.  The classes include:

NOTE: WE HAVE MANY SETS OF THESE TUBES AND THE ONES YOU RECEIVE MAY NOT BE IN THE SAME BOXES OR BE THE SAME MANUFACTURERS AS ILLUSTRATED IN THE PIC, BUT THEY HAVE ALL BEEN TESTED TO THE HIGHEST STANDARDS ON OUR TUBE TESTER. EQUIVALENT PERFORMANCE RESULTS IN YOUR TUBE TESTER OR IN YOUR AMPLIFIER CANNOT BE GUARANTEED DUE TO VARIATIONS IN EQUIPMENT AND CALIBRATION BEYOND OUR CONTROL.  WE USE PROCOMM, EI AND WESTINGHOUSE TUBE BOXES FOR ILLUSTRATION OF THE TUBES IN AN AUCTION TUBE SET ONLY!

TECHNICAL REFERENCE

To help you in your tube selection and installation we have included lots of technical reference information so you can achieve the results you desire.  Although there are many links and valuable information included, we can’t vouch for the results you will get if you follow the advice given, but it may help you anyway.

International Shipping:

Since many of our items are fragile, high value and paid via Paypal, Captain Bob’s only ships via First Class Mail (uninsured, no tracking), USPS Priority Mail International or Express Mail. Priority Mail International is preferred for our customers, since it is faster and safer (tracking) than First Class shipping. We declare that the contents are "Vacuum Tubes" (if applicable) on the customs slip at full auction value.  Auction shipping quotes do not include international insurance or custom’s fees which are the responsibility of the buyer. If you request insurance, your item must be shipped via Priority or Express Mail with an added insurance fee. Buyers will pay custom’s fees on the declared value or insured amount.

You can determine the international shipping to your country by using the shipping calculator at the bottom of the auction.  Choose your country and click the “UPDATE” box for rates to your country.

Captain Bob’s specializes in International sales, but due to customs and other circumstance out of our control, we are not responsible for items not delivered or if the shipment is damaged or lost and was NOT INSURED!. Insured items can be recovered through the USPS. We will assist buyers with their insurance claims, but do not offer any reimbursement from our business. USPS First Class Mail does NOT provide online tracking or insurance for your item, so please choose PRIORITY MAIL or EXPRESS MAIL INTERNATIONAL if you want to be able to track or insure your item!!!! If you use First Class Mail, please remember that we cannot track your item once it leaves our local Post Office, nor can they track your item. Most delays are due to customs holding in YOUR COUNTRY, so check with them and also your neighbors if they accepted a package for you.  Feel free to email us inquiring when your item was shipped and the US Customs Form Number, but please understand that shipping times vary and WE are not holding your item, we want you to enjoy it! Filing a complaint or dispute with Ebay or PayPal after your item is shipped but not yet received doesn’t get your item there any faster; it just puts you on Captain Bob’s bad list.

PLEASE ALLOW 2 TO 6 WEEKS FOR INTERNATIONAL DELIVERY.  WE HAVE EXPERIENCED LONG DELAYS UP TO 90 DAYS THROUGH CUSTOMS FOR ITALY, FRANCE AND OTHER NATIONS.  CHECK WITH YOUR CUSTOMS OFFICIALS IF YOU EXPERIENCE A DELAY IN SHIPMENT.  IF YOU WANT TO TRACK YOUR SHIPMENT YOU WILL HAVE TO USE PRIORITY MAIL INTERNATIONAL OR EXPRESS MAIL INTERNATIONAL DELIVERY, OTHERWISE NO TRACKING IS AVAILABLE.
