Great layout beasleybodyshop!

Having had a quick look at it I see that all the pots are the same value on the layout. No doubt a copy and paste typo.

Thanks for your hard work.

Cheers,

Paul.

Good eye, i will clean it up some more tonight.

Ive gone over it with Aaron's schematic in hand, and it appears to be correct, electrically. I would appreciate it if those much more intelligent than me could take a look see

[ampgeek]

Awesome! Thank you very much for doing/sharing that with us all.

I didn't catch where the grounding bus under the pots hits the chassis/ground point. Did I miss that?

Thanks again,
Dave O.

You guys are so lucky to get a layout.

I had to build mine the hard way off the schematic which I appreciated very much.

As well as advise from TAG members and chassis/faceplate from Amplified Nation.

Gents,

I have been following all JM Sig posts with interest as i do like the sound of this amp. The pre amp looks to be closer to that of a 124 classic configuration with some slight variations ( Mid boost, 4.7uf cathode caps). The shots i have seen of an actual JM sig do not have the .001uf cap across the outer terminals of the Bass pot as per Skyline configuration?
Just an observation

I noticed the same thing, crafty.

I put together a different layout just a few days before this one was posted... Parts (most of them) will be here tomorrow. So I am going that route.

Has anyone posted the voltages? Gotta finalize the bias circuit... Kinda curious if what I have planned will work. I am also wondering if a tube rectifier may be worth it... I have a 5v tap on the PT I'm gonna use.

Good call Crafty, I will try it both ways.

Tony I hope to get those voltages you wanted this weekend, I've been busy with so much stuff I haven't gotten back to this amp other then playing through it

Sorry I owed you big time and want to pay back.

[dorrisant]

Mark, with as much vital info as you post here, we all owe YOU.

That being said, I could use a layout that I'm pretty sure you have... I'll PM you.
