8950 to 6LB6 tube conversion kit with 4 6LB6
Amplifier/Receiver Manufacturer:
This is a conversion kit to replace the 8950 tubes in the amplifier with 6LB6 tubes.
Included are 6LB6 (4) + an 8950 to 6LB6 conversion kit (with schematics and instructions). Instructions are included for rewiring the 8950 sockets from 12 volt filaments in parallel to 6 volt filaments. The 6LB6 is a direct replacement for the very expensive 8950 tube with the only difference being the 6 volt filament verses the 12 volt 8950 filament.

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.
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.
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)
I received the 6550 tubes and thank you very much. Last night I installed all the tubes (5) you sent me and my SUNN Sonic I sounds amazing. Thanks again for all your help.
Today I received the tubes. WOW! my 1962 L-103 can "Scream" again!!! Thanks for your kindness. Best Regards,
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 arrange all the tubes we sell into several classes to make it easier to find what you need. The classes include:
5AR4/GZ34, 5U4, 5V4, 5Y3, 6CA4/EZ81, 6X4, 6X5, 12X4, 35W4, 0A2, 0B2, 0C3
6AN8, 6AT6, 6AU6, 6BA6, 6BJ7, 6C10, 6C4, 6BL8, 6GW8/ECL86, 6EU7, 6J5, 6J7, 6SC7, 6SJ7, 6SL7, 6SN7, 6U10, 6V4, 12BH7, 12AT7, 12AX7, 12AU7, 12AY7, 12DW7/7247/ECC832, 6973/6CZ5, 7199, 6267/EF86, 12AU6, 6CG7
6AQ5, 6BQ5/EL84, 6K6, 6L6GC/5881, 6V6, 6CA7/EL34, 6550/KT-88, 7591/A,7027, 6BM8
6146/A/B/W,6JB6, 6JM6, 6KD6, 6JS6C, 6LQ6/6MJ6/6JE6, 2E26, 6883, 8298/A, 572B, 807, 811A, 1625
Typical manufacturers include the following:
USA Made: RCA, Sylvania, GE, JAN, Hammond, Conn, Baldwin, Silvertone, Delco, etc.
Foreign made: Russian Military, Sovtek, Svetlana, Mesa, Ruby, Electro Harmonix, JJ Electronics & Groove Tubes.
Premium Tube sets usually DO NOT INCLUDE manufacturers such as Telefunken, Mullard, Phillips, Valco and other high priced tubes. These tube brands s are sometimes available as matching sets in the Individual Tube Sets section of my store or may be available in our SELECT or ULTRA Tube Sets.
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.
