I forgot about current draw. I put an amp meter just to the left of where the
choke would be (i used a 250 ohm resistor) and get 98/99 ma. |

PCB for RH84?
Hi
I'm curious about the pcb in the photo. Did you make it yourself or are pcb's for the RH84 available? I'd like to know because I have been gathering parts and will soon start to assemble my own RH84. Thanks Doug (Brisbane, Australia)

The PCB is my own creation.
This power amp is my 2nd PCB project. I built an RIAA pre-amp to listen to my vinyl records and needed a power amp also. Want help - RCA Tube Manual RIAA Phono Stage |
