My new project! MKIIC+
« on: September 27, 2013, 01:37:37 PM »
I started this some time ago but didn't post anything up as I knew it was going to be a long process.

It's finally coming together as in I have all the parts or they are on the way. Just waiting for the headshell and valves now.

I still need to figure out a tidy way of chassis mounting the preamp valve sockets because I don't like pcb mounted ones both for reliability and future maintenance reasons.



I have been holding off on populating the GEQ and the PSU purely for ease of storage but i have all the parts so here's a quick shot of the Pcbs and chassis before i started.



As you may notice the chassis as great as it is didn't come with any mounting nuts welded in so i got handy with some rivnuts.





Then this final part for today is the bit that took the longest. The simulclass output transformer. I spent literally weeks googling for information regarding this beast and learnt i could just use a 50w marshall OT and mismatch the secondaries but then i would lose my 16ohm tap and i didn't want that.

So i did some more research and found someone who had dissasembled an original unit and noted down the winds, wire guage and lamination sizes. I had to make some slight adjustments to the laminations to accomodate the additional 16ohm tap (not present on the original) and sent the information over to BLS transformers and a couple of weeks later this beauty arrived in the post.

Correct it was used for the majority of the sounds on the album along with a roland jc120 for cleans.

I think there was also some triaxis usage too

Just a small update. The headshell has been tolexed. Now for the grill and to decide whether to add silver piping or not....

Annoyingly i'm now on long shifts at work so i'll only get a chance to work on it on sundays from here on out. Hopefully it will be done for christmas.

It takes a lot of research & unfortunately a few nasty shocks during late night sessions (not an essential skill!) to do it!

Definitely not pretending it's anything but difficult to learn, I have a 1st in mechanincal engineering, definitely not dumb but have NEVER got my head around electronics.  Very cool stuff!!
