Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Re: Wait a minute Eli.....

Vinnie, you don't need two switches for power-on. The slow warmup of the 6AU4s eliminates the need to do that. What Eli said is correct - just throw the main switch. Power-down is a different matter. If you have a really long time constant in the HV bleed-down, you might want to keep the 845 filaments on for a few seconds after the HV supply is turned off. I'm not certain myself that this is necessary, but some people say it prolongs tube life.
