Not sure if this is a big deal, but my PT HV secondaries don't read the same. One side reads 279vac and the other reads 286vac. Is that anything to worry about?
Hi,
yes, the cabinet I finished this weekend.
But the PT is now a other question like before.
Not shure that this 7 Volt dif. are a problem. Never recognized such on mine. Do you have hum because of this? Your DMF is new (battery)?
Better some expereanced gives answer.
Hi
do you have 2x 100ohm Rs on the heater fil.? Try a trim, something between 200 and 500 ohms. Could be a better symetrie with this. I had this twice. the trim stops every hum wich is from the heater fils.
I've got a 500 ohm trim pot in there now. It is not affecting the hum. I can hear it affecting a buzzier type hum if I turn up the volume (no guitar plugged in) though...
Hi,
excuse this question: do you have maybe a heater fil. CT and this at ground too. If yes, please choose only one fil. grounding: the CT or the 500 ohm trim.
I had a similar problem. I used a NOS Thordason Transformer 540CT @ 260mA. I ended up using the vvr to limit my top voltage, it works. I am tempted to remove the upper limit on the vvr and rebias to get closer to the AC30 sound.
