Okay,
So here is what I have been up to over the past 2 months!!!!
Most of that just spent trying to source the parts form all over the world... one of the disadvantages living in Africa...
Some Background.
I had a client who had a bunch of old Neve 1271 cartridges he bought from a guy. The 1271 for those who don't know had a BA183AM board a 31267 on input (I wired them as per the JLM diagram when I racked them as pres ) and an LO1166 on Output and was typically used as a line amp much like the 1272.
He was sold them as working... which turned out not to be the case since someone had tried to stuff the rest of the cards, but couldn't tell an emmiter from a collector and that meant I had to rebuild the 'working' cards and I recapped them with some quality BC axials while I was at it.
I had 8 of these little beasts to rack and he needed them to take up as little space as possible... so we went with a 2U rack per 4 channels, each with the JLM Hot Rod Mod (Thanks to Greg for the boards and Joe for the design), Go Betweens, 2 DI's per rack and in the end it all got rather hairaising and required a lot of planning to fit it all in.
On Joe's advise I decided to keep the PSU onboard and build an external transformer box, and put the fuse on the transformer box for easy replacement and a nice lengthy cable to keep it far away and it is amazing how quiet they are now.
I designed some custom panels which I had engraved and I had Purusha silkscreen the rear panels for me as well as provide the racks.
All in all I think it turned out just spiffy, though I must warn you... don't try this at home... with all that off board wiring it took double the amount of time I budgeted for!!! But it was fun and I'm glad it is nearing the end and will end up being put to use making some fine sounding recording!
Soon I get back to my own DIY and that LA-2A is looking VERY tempting
Cheers
Matt
