Title: TOA RX-216 mixer console
Post by: wavebourn on October 19, 2006, 05:00:22 PM
Hi fellow Gurus;

is it possible to find schematics for this noisy (as I heard a rumor) vintage beast?

Anyway, I am going to rewire it completely using tubes for intputs, but anyway schematics would help.

It has a solid frame and nice input/output transformers, and plenty of room inside. I did not receive it yet, so can't tell for sure if potentiometers are still good. Also, it has a reverberator inside called "analog delay". What does it mean, a mechanical spring, ore some kind of charged cells?

I'll keep you informed about the project.

I'm guessing that if they said analog delay, this would probably be a recirculating delay using an analog bucket-brigade delay line.

If so, it might be better to remove the recirculation, and have the delay drive a spring.

Thanks Bacon, I'll defenitely remove it, I am just curious what it means, "analog echo".
