Progress.
Man ! This thing looks sharp in Mikey's cab.
Power supply 64uF - 7H Choke - 32uF - 20k - 20uF - 10k - 20uF - 10k - 20uF
B+ at about 410. Feels loose in a good way. Not overly bright.
Used mainly stock 2204 circuit with Martin M, Miles & Jana's mods.
Martinizer presonance.
External bias.
3 way switch for 3rd stage input level.
Switch for 100k or 50k + 1000pF CF.
Switch for big 150uF catthode bypass.
Biased hot.
Gonna play her for a month b4 I change anything.
Still needs foot switch/relays fitted.
Very versatile - can get great singing cleans - almost acoustic.
When you kick the gain in ... she's a beast.
Dirty Girl.
Many thanks to all who helped make this happen.
Next up - a straight up Plexi build with Mikey - ampmike.

Awesome!
You have a plastic protector of some kind on the big hole for the PT wires. What is that and where can I get?

Re: Marshall - It's Alive & Kickin
The plastic edging is called edge trim. (grommet strip in English)
Pretty sure I got it from McMaster-Carr.
McMaster # is 85085K4 $6.13 for 25x1ft lengths.
Comes in handy - that's the second PT I've fitted to this chassis.
Naturally they required different cut outs.
Hence the grommet strip.

Re: Marshall - It's Alive & Kickin
With that tight and clean layout I'll bet it sounds just like that but not so clean really.

Re: Marshall - It's Alive & Kickin
Did Mercury ship the OT with the brackets sandwiched between the core and end bells? I'm used to seeing the brackets on the outside...

Re: Marshall - It's Alive & Kickin
Yeah I looked at the brackets on the OT too.
I got it through someone else, so I'm not sure that it is "as built"
Sounds great though.
Of course everything matters in an amp - I just think that the OT is one of the biggest factors.

Tube holes
Hey Guys,Starting my marshall that Bob sent me.Thanks again Bob!!!I need to add a octal or can cap hole.Is there any minimum distance for power tubes?Could the glass be 3/4 of an inch apart?On the other hand I could put the can cap tight up against each other as a choice too.Just want to check before I pop the hole in,Thanks Guys

Re: Marshall - It's Alive & Kickin
Just wanted to say I built the wrecks but really dont play them much.My metro plexie I play almost every day.I think the marshall circuits for blues and rock just do it so perfectly.I put a lar/mar and it sounds great at any setting.You cant go wrong building one.Im starting the 2nd one now with Bob.Ill try to do pics as I go and sound clips when it up and running,Thanks Mikey

Looks real nice Bob!
Clean to mean a good thing!:D
One of these days I'll build a Marshall.
Have you used the JJ caps before?
Been curious about those.
