Issues with recent Marshall clone

[Marshall_Mark04]

I recently assembled a Modulus Marshall 50 watt clone DIY kit. Buy I only get sound through my tubes, or output transformer. No sound at all through my speakers. I noticed one power tube seems to red plate in one socket, and in stays in that socket. Any ideas on how to fix this issue?

To the forum.

Smart folks here. Someone will be along shortly to help you out.

Can you think about your question please and rephrase it? I have a hard time deciphering your meaning. Not a put down, just hard to understand it.

Show a pic of your output jacks. Are they grounded?

I believe so. I ran the continuity test on my multimeter to check the grounds and it checks out.

Take a nice well lit overhead of the whole thing, then one of youre socket and jack wiring and then one of youre power tranny wiring. Too close and we won't be able to see whats feeding what so lets start there and if we need close ups of anything we can ask for them.

Continuity function will simply not do for circuit grounds. You should be measuring resistance to determine whether a ground is good or not. Set your meter to resistance and touch your leads together. They shouldn't read more than .1-.2 ohms. What ever they read is when you do this is what you want to read when you test a circuit ground.

I got it working. Turns out I accidentally wired my impedance selector switch upside down. lol
