"For high voltage supplies an indirected heated rectifier tube works well and needs only a filament supply."Don't forget it will also need a socket, take up space and get hot. However, it's a good idea if you can accommodate it. My present amp uses SS rectifiers because I need the B+ voltage but I use a TV damper diode tube to give a delay of 30 seconds. Voltage drop is only 8v.

- True, but it's conceptually simpler than a multicomponent solid state delay circuit.. :-) nt - JimL 17:56:36 08/09/06 (3)
- I'll tell you what else is conceptually simpler than a multicomponent solid state delay circuit . . . - Ray Moth 19:11:59 08/11/06 (2)
- Hmm, interesting concept - if you need a bridge. nt - JimL 10:11:51 08/12/06 (1)
