Amp Has No Sound!

[LLL]

So I plugged my guitar in, dimed all the knobs (as you do Marshall-style), cranked a massive power chord, and POOF!

Took the chassis out and this is what I found! Figured I at least blew the HT fuse...

Anybody figure out what's wrong?

I don't see any speakers in that pic!

Well the first issue is youre drinking a glorified wine cooler. After that Ill agree w Dave

What is going on there in the lower left corner of the gut shot? The bottom, near the AC in and the left most fuse looks funky.

Might just be the picture.

Either way, good luck getting it sorted out!

You were drinking Seagrams?

Purple wire from somewhere to nowhere, up front, center, to slight left.

That's the negative feedback wire. I put it on the 8 ohm tap.

But seriously folks, nothing wrong here... pics of my installation of new Heyboer/MojoTone OT.

Thought it looked funny all exploded with wires everywhere.

While I'm in there, gonna replace the preamp filtering cap (pretty difficult to get to with the connectors being underneath the turret board).

Already replaced the poweramp filtering cap.

16+16 uF - preamp filtering
32+32 uF - poweramp filtering

For late 60's Marshall squish... not super-tight like a modern amp.

Seagrams is good.

No drive pedal was connected.

No drive pedal was connected.

Doesn't really need one, unless I'm going for metalz. That V2 .68uF cap really ups the gain from the typical plexi spec.

History-wise, apparently in 1968 Marshall placed said cap on some amps and not others, and dropped the cap altogether in subsequent years.

My initial comment was a tongue in cheek move based on earlier dialogue...

That's why you play with your organ.
