Space-Tech Labs model Q-113 balanced output pre-amplifier.
$555 includes shipping and paypal fees.
For a full price sale I will include Bendix 5852 rectifier tube (This is a premium 6X5GT) and a pair of radiotron 6f6g grey glass tubes from the 50's. A $100 value.
All hand wired. The big tubes sound much more natural than those tube pre-amps with small tubes like the 12AX7.
Please visit Albert's website

I have taken great care of this pre-amp. I am original owner.
In addition to the pre-amp you will get the following tubes:
(4) Raytheon 6G6G
(2) RCA 6G6G from 1954
(2) RCA VT-198A (premium 6G6G) from 1958
(2) EL34 Russian sovtek winged C (not NOS)
(1) GE 6X5GT rectifier
I am going to copy from his website:
Line stage balanced output pre-amplifier
Using the 6G6G as both the amplification and 6L6G as output buffer section, this unit features superlative mid-high sound, built with a 6X5 tube rectifier. This gives you the best ST size tube sound with a low price. All hand-wired to the highest possible standard.
Organic pure tube non-feedback design, as well as with our copyrighted FLEX-TUBE design, you can put in over 10 different type of tubes as output and fine-tune the sound to your desire. The front tube can change from 6G6G to 6V6G, 6K6G, or 6F6G, which will alter the gain as well as sound qualities. A total of 4 x 10 = 40 tube combinations can be used in this pre-amp, buy one pre-amp and have 40 possible different sounds.
