FOR SALE: Tube type preamp /  tone controls.

Here is a cool "signal processor" of sorts.

It has those screw-on coaxial mono audio connectors of yore, usually used for 
mic level signals.

Has two tubes, 6SQ7 and 6SN7. Two Allen Bradley pots with black "chicken head knobs"
for bass and treble cut-boost,   and has beautiful construction using cloth-covered wire. 
No AC supply on board but DOES have a dual 20 uF + 20 uF at 450V DC can capacitor.  
Requires about 250V DC at 25 mA and 6.2V AC at 1A. Includes numerous capacitors and 
carbon composition resistors.

Small aluminum chassis dimensions: 6.5"  X  5.5"  X  1" tall.
Overall 4" tall with parts. Pictures available on request. 

Available for $15.00 plus shipping.

Thanks & 73 de AF4K, Bry
