I Can't Stop! Check My Attempt?

Thanks, thanks.

I'd rather build the 6G3. I'm just trying to practice understanding schematics and circuits.

Does my modified 6G2 look okay? I'm trying to better understand how to implement solid state rectifiers.

The part number for those diodes is 1N4007.
If it was my amp I would use 4 Vishay brand UF5408 fast recovery type diodes to get the switching noise hash out of the power supply,if not atleast add a ciraimic .01 @ 1000 volt cap across each 1N4007 diode .
Also note that dropping the tube recto will add about 45 volts to the overall B+ voltage so you need to think about if your main filter has the needed voltage rating and the different sound the amp will have if atleast the preamp power supply resistors are not changed to keep the voltage near stock.

I just noticed the 6G3 schematic doesn't show a cathode resistor. The standard would be a 250 ohm 5 watt.

Thanks all for the help.

I got a little bored at work and drew a layout up for the single-channel, cathode biased 6G3. Not sure it's legible, but it's a try!

Other than using a nine-pin hole/socket, what all would I have to change on the design to use EL84's instead of 6V6s? Would I have to dramatically change the power supply or just a couple of voltage dropping resistors?

[Teleguy61]

I'd put a 250Ω/10W and 50µF cap on the cathodes of the 6V6s.

Like this?

Thanks for the help everyone!

But...but...there's an unused triode!

[sluckey]

Actually according to the layout there are two unused triodes. By relabeling V2 as V1B, he will only need two little tubes.

[LedZepp007]

In fact, there are two unused triodes. So, I could go with two AX7's, two 6V6's, and a GZ34.

I will have an extra space for another preamp tube. What about an EF86 channel?
