Reel deep thoughts...
As per the idler tensioner, yes it's spring loaded and it is as far clockwise in it's slot as it will go.
So I wonder if it just needs re-clocked…the whole assembly. I can’t recall if the assembly mounts to the transport plate with 3 or 4 screws. I think 3. So maybe it needs rotated 120 degrees clockwise…
Modifying the daughter board eq modules is easy it appears. Acccording to here: http://www.uneeda-audio.com/ampex/ag440_equalizer_pwa.pdf
The difference between -01 and -03 is two caps. Actually turns out I have a pair of -03's and the rest are -01's.
Yeah okay…I was recalling it was pretty straight-forward.
Record card daughterboards don't need to be modified?
Nope. Nothing changes with the logic, nothing changes with signal that needs amplified, what changes is the EQ curve necessary for best response. And that’s on the daughter board.
That extra power plug is not the AC to the control box. It's a bit smaller than that.
Okay. It’s like the same size then as the power input on the transport supply on my MM-1000. Well where does the cable originate?
I should be honest about my intentions with this machine. The plan is to simply get it rolling tape like it's capable of, and recording on every channel, and then sell it. I hate to give up on it, but I found a MM1100 for a good deal, so planning to spend my time more on that machine. Just want to get it as least running for the next person who uses it.
Well I’d do the same thing all day long, just make sure the MM-1100 has had the field service updates to address the known problems with that model. They are as reliable as an MM-1200 with the updates. But an MM-1000, 1100 or 1200 is a better machine than the AG-440-8. Your AG-440-8 looks to be in pretty good shape and mostly complete, totally complete functionally. I just see some cosmetics missing.
