Josh thanks for getting me started with chassis and transformers. I'm sourcing all the parts and had a few questions. Are the 220pf in the treble circuit and .01uf caps in the tremolo circuit Wima style film caps? Can you recommend voltage and the lead spacing to fit the PCB. Link to Mouser or other would be great. Also what type of switches do i need for the reverb and tremolo circuits. One more, what type of tube sockets are best to use with the chassis. Remember, you said the need paitience is just beginning. Thanks
I know, I know. 🀣🀣🀣

There's a link to a Mouser BOM on the doc page: viewtopic.php?t=25550

Make sure you're using the PCB 1.4 docs.

I like Belton Micalex tube sockets.

Typical mini switches should be fine for rev/trem.

Thanks,
Josh

Josh is the 3.3uf 63V capacitor in the Mouser BOM in place of the 2uf cap fed from V2 P8?

Yup. I'm surprised I didn't put a note about that in the schematic. Eh, maybe some day. πŸ˜‰

Either value is good. I did put a note in the regular BOM: "Higher value for more bass."

That escalated quickly! πŸ˜‰

Start a thread for your build. Keep us posted on your progress, and try to compete with my heater wiring:
