Thanks for your numerous replies :) The PPB is great and I'm glad of it's size. If it were much bigger, it just wouldn't fit into the sk1.

I'm using 2 pairs of dual gang and it's not ideal." I searched far and wide for a 4-gang pot and only ever found one Tue, 10 Nov 2009 01:45:21 GMT gmeredith1 http://launch.groups.yahoo.com/group/CasioSK/message/558 http://launch.groups.yahoo.com/group/CasioSK/message/558 Yes, I had a lot of problems too, trying to get the input gain down - the SK puts out a very hot signal.

Sorry I missed your posts, gosh, I go away for a few days and this place gets exciting :D Glad you Mon, 09 Nov 2009 18:00:25 GMT luke http://launch.groups.yahoo.com/group/CasioSK/message/556 http://launch.groups.yahoo.com/group/CasioSK/message/556 The keys cut out after approx. 400 strokes. Which is rubbish. Any advice on this one? On the PPB, I replaced the 741s with 5534s and it has cut the squealing Sun, 08 Nov 2009 19:23:53 GMT luke http://launch.groups.yahoo.com/group/CasioSK/message/555 http://launch.groups.yahoo.com/group/CasioSK/message/555 There's an APO mod on Electri-Fire's site which works a treat. I've had the demo going for about 20 minutes and the crazy is setting in now...

I actually found the source of the problem... I'd placed all of the res pot wires after a trace cut instead of before it.

It seems to be working reasonably well. However, it squeals like crazy.
