Finally received my non conductive, plastic screwdriver set from ebay today. It took 7 days to arrive from tiawan. It was well packed and no problems with delivery, shipping etc.
Inside the pack was a plastic wallet with 4 different plastic screwdrivers. Quality is not brilliant but adequate and there is one screwdriver in the set that works perfectly with the VCO tuning and trimmer adjustment pots.
So thanks for the link from bartleby.
I'm still waiting for a reply from Bruno regarding the tuning on my minibrute. Not sure if the unstable/ drifting tuning is down to it being very hot at moment or that there is an ongoing problem that needs addressing.
So Bruno please reply to my emails as I have sent you three and I have now been waiting over two weeks for an email back from you!
