Sophia Electric has supplied its early 845 amplifiers with this 5Z3P Octal 8 pin tube base(same as 5U4/5R4) rectifier tubes.  I got a few units of this great sounding 5Z3P rectifier tubes in stock for Sophia Electric 845 amplifier tube replacement.

I tried it on my single ended 2A3 amp and 300B amps, it does sound amazingly good.  For the asking price of $49.99.   It is a killer deal. 

Please check my feedback for happy buyers' feedbacks on this great tube.

Requirement:  While vintage traditional 274B requires 8uf first capacitor in the power supply after the rectifier, this 5Z3P can take unto 22uf at 450V DC.  Max current is 140ma at 450V DC.

Price is for one vintage Coke bottle shaped 5Z3P tube, that is a direct replacement for 5U4G 5U4  5R4 rectifier tube commonly seen in a 300B 2A3 El34 KT88 6L6 6V6 single ended tube amplifiers.

In NOS(new old stock) condition and tested good working.
