Anyway, due to my inability to realise where a fuse goes, I found myuself with a power transformer (100w) for a mrshall-esqiue style build. I also have had a jtm45 chassis lying around I'd meant to do a boring jtm45 in as a "intrroduction to turret builds" project. However, the jtm45 is a grandpa amp, for people who like blues, strats and ignore massive racism whilst extolling how great Eric Clapton is...
So, it's about time I took something I want to build and add some stuff to it. Going a bit off the beaten path, going off grid, and just using that as a way to learn a bit more.
OK, but at this stage, I still didn't know if the transformer was still good. I mean, I thought it was, but you never know. So I bolted transformer in, did a rudimentary connection to the mains, and then measured the HT windings and some others. Success! Not dead! And thus, a project was born!
I'd been toying with the idea of making a clone of the Fortin Meshuggah amp (yet another modded Marshall(tm) if you look at the schematic) so I kind of decided that I'd go down that path, and just use things I had, like the power transformer, and the chassis which fit together so nicely.
So, that was phase 1. I was going to build a clone of it. Awesome.
And I was going to do my own turret board as, well, why not...
But then, then things started happening...
Then I started thinking, i mean, what if I made it footswitchable? Wouldn't that be cool?
This kind of opened the gates to feature creep somewhat. If you've ever worked in software, you'll know "feature creep" is where you get asked to build the program equivalent of a shoe. And then little things keep getting added, and before you know it, you're now making a shoe with jet engines, wheels, little wings, a satellite dish, miniature kettle and an anchor instead of brakes. So yeah, more things got added to the list.
So, boost board, cool, we can do that. But maybe I'd like to footswitch the 2 "channels" instead of swapping the input jacks to get the effect. OK, I reckon I can do that. Looks like it'll be a doubnle relay as channel 2 has a capacitor to ground. OK, I can do that...
Then, then the next idea happened about 47 seconds after watching a lee jackson marshall mod video.
My brain tickled, and I asked "the" question. What if I wanted even more gain (because the meshuggah amp definitely does not have way more than enough gain already. And the boost won't have added any gain either at all... *cough cough*). That'd be a great idea. I can also make that switchable.
No matter though, it's all about the intent.
And to make the intent more intentfull, i went of and wired all the heaters to the sockets. And thus, mistake 1. I forgot the power tube sockets are bolted in 45 degrees off to what I am used to. Cue me wiring the heaters to pins 1+6 instead of 2+7. Stupid. Easy fix having spotted it now, but still stupid. Stupid as in if I hadn't of seen it now, it may well have caused some kind of fun tube or amp death and maybe magic smoke at some point. However, I'll never know as I caught it before it was too late. Phew!
So there we have it. I've got ferrite beads on order, magical mustard caps, some sick as hell R
ussian radiation pilot lights, a 50w slo output transformer, 5H choke, and many other bits (actually, this is a lie, I have them already, but i wanted to build up suspense for next post)
I'm going to taking my time with this one, seeing as I'm doing a few things for the first time here, and this one might take a bit longer, but that's ok, as I'll hopefully learn a ton as I go along.
