Ah the GX-M10, fun decky! Amazing how that IPSS system works isn't it? With al the mechanics, and electro-mechanics, and early day logical port technology.. You kind of would expect it to glitch, but it never does. I did a full service on mine. If you do: be aware there are bipolair elco's hiding on the IPSS control PCB. And yes, that counter belt is critical. Mine was mint and fully serviced, but I couldn't sell it for much. No idea why really. I mean, it's a GX model, with awesome fluorescent LED indicators and the IPSS system.

Thanks! Yeah, I replaced the counter belt without issue, as well as the capstan belt. It's the last belt on the back left that activates the auto-stop that I haven't replaced yet. I won't do full service on it (I'll leave the PCB alone). That's a bit out of my comfort zone, I'm afraid. And yeah, that fluorescent VU is gorgeous.

GXC 730 seems very stable. After repair and modification.

and modification.

What sort of modification did you do on your GXC-730?

 

[Sinder]

Modification of playback and recording amplifier. I didn't like the -3dB on CrO² tapes. In addition, I get saturated with CrO². No problems with Fe²O³ tape. I did a little searching and am currently still fine-tuning it. Experiment with Darlington BC517, BC550 etc. Especially with Dolby, since the MPX filter is permanently integrated there. The device falls off at around 13kHz. As I said, I'm still there.

, I get saturated with CrO².

Ah yes! I had that problem with the GXC-710 in particular (same head and at least most of the amp). With 2SC1845's it got a bit better, but still not great for hot recordings. Let us know if you find the winning formula.
