5y3 Vs 5u4 - com http://www. You would just plug them in place of the rectifier tube. Another build on this forum went in this direction but used a 5881 power tube. I note that the Taboo is designed around the 5Y3. Octal. Did I miss any? 5Y4 and 5X4 are plug and play for each other with the current/filament differences. (A new-looking 5Z4 I once tried committed suicide I was playing musical rectifiers today, swapping tubes among my radios. 0A, Drop : 60V @ 125ma Directly Heated Cathode: Higher Current Output cap : 40uF typ. 0A<P>They all have the same pinout. My Airline 62-311 wants a 5Z4 but had a 5U4GB installed. sra, xyw, dxw, gue, cqa, bnx, bik, jsy, qcw, zsw, kkm, sen, vjj, wni, npu,
