hi folks,
I am building the JE labs 2a3. I got the ps and driver tube all wired up. the edcor opt are on order, 3-4 weeks they said...busy time for them. I listened to the the driver stage with a 6sn7 and took the signal just pass the coupling cap. sounds very nice, great bass. without the 2a3 tubes, not sure of the ps output. its around 450 volts...ouch. the voltage at the 6sn7 anode was 114v. I figure once I have the 2a3 installed, I'll take measurements and go from there. next is the cathode cap and resistor on the 2a3s. I am planning on going to two filiment trannies on the 2a3 at some point and adding plate choke to the driver stage. open to any suggestions for changes or additions to the amp. so far so good. see ya all later, jeff |
