:BangHead: So I am building a SE with a pentode triode pre (6U8A) and Russian 6P1P anyway Antek AS-05T200. 2 sets of heater taps.
I want to go in my theory IEC to fuse, to switch, to power primary, to stand by and then bring the heater wire for the light (6v light)?
I would like to find a schematic for this.

I would just drop the standby switch. We don't need no stinkin standby. :l2:
The way you proposed has two switches on the primary side.
If either switch is open, the circuit is off.
Unless I misunderstood what you meant. :w2:
You can just wire your 6V lamp to your heater wires.
When your switch is on the lamp will light. :icon_biggrin:

OK , I get the heater to light part and I get the part about not needing the stand by but it's getting one now ( drilled)
I might leave it in stand for a while sometimes. I just need a schematic for the standby I guess.

Standby can go between your rectifier and 1st filter cap. :dontknow:

Ok thanks Paul , I went to valve wizard and read up on it. Maybe I can use the switch for ? Bright switch ? All though it is right next to the power switch. :cussing:

After I read that I was shocked that standby switches are still commonly used.
Bright switch, NFB loop cut switch, either sound better to me than a tube damaging standby switch. :icon_biggrin:

Thanks :l2:

If I was still gigging, I'd still use the stand by switch.
ALL the blues guys that I hung around with/saw play in Chciago, that played Fenders (most did) or another amp if it had a stand by they used it. And they had always used it since the 50's. Many of them were big names on the blues scene in the '50/'60's. Guys that Clapton, Page, Jimmi H., J. Beck, etc..... loved.
I NEVER saw a Fender amp go down on stage (although I'm sure it happened) and their amps/tone was fine. So was my BF SR, and I played a lot with that amp. :dontknow: I'm not trying to say Merlins wrong but if the tubes were being affected to the point of the sound degrading and/or dying they would have heard it/known it. They made their living off of playing and they were too many of them for them all not to hear it and/or figure it out.
I did have a 6L6GC's heater burn out on my BF Dual Showman (1st amp) but it still played. I could hear that something was wrong right away but didn't know what it was. A guitar player came by our little gig who played for Buddy Guy and Jr. Wells for years and he sat in and played through that amp with the bad 6L6GC. When he came down I asked him if he thought my amp sounded funny, he said it sounded fine. :dontknow:
My BF SR lost a faux heater CT 100R, at home, changed it and the bad 6L6GC, worked fine again for years. :icon_biggrin:

Please be careful and do not electrocute yourself.
Wall-power is NOT something to guess at. Some folks think you can not safely learn it on the Internet.
