New pots installed and test fitting the turret board: I then wired up some of the on-board connections, and then began to wire up all the flying leads: I figured, I was already so deep into this, I had better at least source some original NOS mustard capacitors, which many people believe...

Marshall used a number of different kinds of materials for these boards during that time, depending on what was on hand. Some was solid, some had holes, some was red, some was brown. I sourced some new phelonic board material, that looked period correct and staked out a new turret board: Then...

Ok, onto the electronics stuff. I spent a fair bit of time on the existing turret board trying to learn how it all worked and how to use the multimeter I had bought for myself. I also began sourcing parts I thought I would need. At some point I discovered that the reason the amp was noisy...

Here is the cab in the process of being recovered. I have to state at this stage that all of this work was being done on my dining room floor, as I lived in a simplex at the time, with no access to a garage or workshop. And here is the head box and empty cab, with their full livery installed:

Ok, so here's a little bit about my first foray into valve electronics. I acquired a 1969 Marshall 50w guitar amp as part of a trade. The amp was a bit of a basket case cosmetically and electronically. It had been recovered with black vinyl at some point in its life instead of the original...

Hi Lanties, Thanks for the welcome! I'd be very glad to share those projects. I did actually document them with photos as I went along and posted them on another forum I belong to (Guitar Forum SA). Photo's coming up.

Morning gents, This is my first post so I guess I better introduce myself. My name is Shaun, I live in Durban and I'm a guitarist who has a budding interest in valve electronics, particularly guitar amps. I'm still very much a beginner, having only completed 2 projects, my first being the...
