Just finished building a Ultra Champ type amp sounds pretty good so far and its very quiet. I am curious as to the warm up and stand by switches as when I turn the power on which hits the power tranny and rectifier tube I have enough power to hear a signal when I play my guitar it comes up to full power when I hit the stand-by after a few minutes and everything seems to function well. Has anyone else experienced this?

Also I used some a upgraded power transformer so I can experiment with different tubes 6L6 types mainly and a dual taped OP tranny to facilitated this. Currently running a JJ 6v6 with a plate voltage of around 406v with a 5R4 rectifier and am looking at tweaking the cathode resister to cool this some. Will post some pics when I get time. Really enjoy the forum. JGK

Let's just get this straight...

You are saying...with Power ON and Standby ON (meaning high voltage off...the amp is in Standby mode), you are getting some amplified signal from you guitar plugged in?
