so once you get a working version, how long will it take you to actually assemble these bad boys?

I figure 20-30 hrs or so... the chassis and the turret board will be laser cut in bunches so that will save quite a bit of effort...

Bitchen !! :thumbsup: :thumbsup:
I love how you have the vactrols locked down there. I build two identicals and theyre not identicals.
 
Ok, so here is this week's update... Cut, drilled, staked w/eyelets and populated/soldered the relay power board and also drilled the chassis to accept it (PITA - glad this will all be done in advance by laser on my next chassis!). That board has a 1A, 50V bridge rectifier and a 7806 voltage rectifier and I had to use 3/32" eyelets for those. That is 1000 uF electrolytic cap off the board. The red wire from the last relay DIN connects there and I need to run a wire to the XLR plug to power the foot switch relays as well. Black wire goes to ground. You can also see that I've drilled the chassis and installed a 6VAC PT - that'll connect to the relay power board and the on/off. Now all chassis drilling is DONE! I need to do the input jack wiring, wire in the board, put the EFX loop in and then I can build the foot switch and get rockin'.

Here are the lastest progress pic:

Cool !!!!

btw Steve, my tube and parts seller now has these little PCB boards for Finder/Takamisawa Relays to make guys like us life a bit easier. Let me know if (for the next amp or so) you want some of them . . .

Awesome! Oh man - that would save a lot of effort!

NICE!!!
Solen Fast Caps I see... <twists_moustache>Very interesting</twists_moustache>

Yup! Also SOZO Vintage caps, Riken resistors and PRP resistors sprinkled throughout... for different reasons... :yes:

I thought I was nuts, but I can hear the difference between different cap brands/materials. It's NOT subtle... LOL! :D
Haven't played around with different resistors yet.

Oh yeah... and that Sozo break-in period... it's no joke.

yup, I experienced that Sozo break in period also - the more you play your amp just starts sounding better and better!
 
looking great man, I'm seriously hoping to get a chance to hear this beast! :rock:

Yup... furthering the break in process as we type... ;)

You will - getting close, hang in with me! :D ;)

You DA MAN, steve !!!
The most revolutionary Marshall Madness !

are there any posts you made here regarding the loop ? (if there is going to be one)

If so, I'll look for them, just curious

What do you think of the Larry Loop ?
 
Whoa! I just checked in...and I see light at the end of the tunnel :thumbsup: :rock: Looks freakin' awesome!!

Can't wait to hear this sucker Steve! :yes:

Thanks man! The loop is a series/parallel switchable one. Different than Larry's. I've heard Larry's is a great parallel loop.
