RS-101 modifications

"Have you seen the prices of the Roland RS-505 and the VP-330? Getting high aren't they? So this is my attempt to turn a rather battered old Roland RS-101 into a new and very useful machine.

The unit arrived in several pieces when I first got it. Over the period of a few months, when I could grab the time, I fixed it up and then modified it.

I upgraded the power supply, added the human voice circuitry from the VP-330, created a balanced stereo output, put a proper mixer for each tone, added an ensemble bypass switch for each tone and added the ensemble modulation section from the RS-505.

She's still not a pretty thing but a very useful addition to my little studio.

There are some more details about the modifications with each picture."
