Attached pic 6V6, it's OK?

Joshua_G · 14th December 2012, 02:57 PM

Have anyone tried 6V6 preamp with transformer output?

@merlin
Schema 6v6 ok.
Try no gnd, full gnd, to see. Use fuse, even glass one for now.

I will use two diodes in series for voltage doubler, I changed all CCS area: resistors & both DN2540, also I will included all zeners 12V 05.5W that I didn't installed, local shop don't have 500V: could I use two fuses in series 100mA 250V or in parallel?

Use two fuses 100mA in series with 2 cm distance between their holders. So they can interrupt without arc.

Can I use zeners 12V 1W to replace 0.5W?

Salas · 14th December 2012, 05:16 PM

Yes

Salas see attached pics, If I don't see I don't believe: 300 ohms PSU Caddock MP820 with big heatsink.

I have connected the regulator but the red LED has not lit and neither I have voltage at the output

First I will change Q6 2SK117GR to see if LED lits.
