Hello,
I can buy an Ampro 730 reel to reel machine for very cheap.
It's in a non working condition, so I thing I might use the PSU, output transformer and tubes for a building project (if possible).
I was looking the internet for info / schematic for the 730 and the only thing I could found was the 731 schematic.
Do you know what's the different between the 730 and the 731 models?
Does the 730 working with the same tubes as the 731? (12ax7, 6au6, 6aq5 ans 6x4).

If you have to have it shipped to you it won't be cheap. Better to repair it and use it as a tape recorder.

Same tubes. Later tonight I'll scan SAMS 133-4 and post a link.
