Marshmallow's build thread

[Marshmallow]

Figured I'd kick off a fresh thread to mark the new chapter in my building journey. With a new country comes a new approach, right?

Thanks to friends who chipped in with power tools, and with a decent job, I'm all set up to make amps for myself without having to sell them. Also got a bunch of these electrical wires from a good friend.

Few projects coming up, I'll start with the more boring ones. Build approach is still based on what I did in Japan. I completed this amp about a month ago or so ago using one of the chassis I brought with me from Japan. This build combines elements from different circuits: it's got the reverb circuit from a Custom Reverb, the preamp from a Two Rock JM amp, and the OD section from a #60. The result? Pristine and touch sensitive cleans and OD. OD is raw and the reverb circuit is the cleanest circuit I've heard in a while.

Will post gut shots in the next few days (If i remember)

Few minor details:
Gain Structure switch
Footswitch
Negative Feedback
2 parallel speaker outs with impedance selection (4,8,16)
Effects Loop
Individual bias test points.
2x 6l6,
Hammond PT, OT, Reverb and choke.

Tolex, grille and corners from LiveSound, running JBL E120.







I'll try upload build processes here as I go.

Look awesome, always impressed by your work. So are you back in NZ now?

Rad sounds like a cool amp
Wouldn’t mind doing a demo on it

[jeremyb]

Sounds beyond rad!!

[JoeBlow]

I want to hear it The description sounds great.

Double forum demo in Northland.

Keen for a gearfest!

Recently acquired a collection of NOS parts yesterday dating back to the 70s. Enough to last me many years of amp making. From Philips resistors, Yellow mustards, Matsushita and National capacitors, terminals, fuses, solder, solder stations etc. A shop was closing down and I picked what I needed for a fraction. Pretty good deal I must say. Time to start building I guess.

Shit a brick, score!

[robthemac]

Epic.

[Marshmallow]

Thought I'd share this as well. 5e3 style circuit - 20w (classictone PT), SS rectifier, 6v6 with minimal wire crossover.
Yellow mustart caps, industrial wiring. individual bias test points and single ground.

Here's another 5E3 with robinette mods and bigger chassis.

Been enjoying these smaller amps lately. Maybe I'll try a gibson circuit haha.

[jeremyb]

I wouldn't even play that, I'd just leave the open chassis on display as art.

Phwoar, where'd you "aquire" these?

Axcent Audio! My mate jeremy was working there. They fully sold the business I think and had to clear out.
