it should be here in a couple weeks, will be shipped in a week or so. i have more details on it. it is a optimomd 9100B/2 apparently it does have Card 10 in it and it has the LED upgrade 🙂
from the sounds of it and the condition described it has likely been well maintained over the years.
i may have got lucky on this one.
I got it for $800.00 packed and shipped to my door.

Chances are it has not been done at all, or have been done many years ago !
Also check out what version of filter card is in slot 1, and what colour pre emp modules it has installed on cards 4 and 5, and check that the pots are not crackly !

Total posts : 45366Welcome to the Optimod Club! The caps in the 9100B should be fine and operational, I’ve got a 9000A and other gear from that era chugging along just fine. Eventually it’ll want new ones but I’d be surprised if it needed them now.
Total posts : 45366from my understanding is it was maintained well at it’s previous home, since it has the LED upgrade that likely it had a recapping at some point in the last few years.
I’m going to buy a greek CQUAM 20 watter and run about 5 watts average into the coupler like i am now for the neutral loaded carrier current system i have. it’s a B2 so it is stereo i just need a CQUAM Tx to go AM Stereo and me and my friend both have CQuAM Receivers. i have a TX11B and a TM152, he has a SRF-A40? he has the sony walkman CQuAM Rx.
I will be in two clubs soon the Optimod club and the AM Stereo Club 🙂 I will be the only CQuAM station in Denver, lmited as it might be still CQuAM none the less.

There is no guarantee that the caps are fine, especially if they are old, don’t assume they are ok !
This is where a esr meter is valuable here, as the caps can be tested in circuit, to give a good indication of condition.
The fact that the Optimod works, does not mean is sounds at it’s best.

Total posts : 45366Paul does bring up a very good point. I always at bare minimum visually inspect the caps for bulging or leaking. If it passes my eye test I plug it in and wait for the smoke, if no smoke or buzz I assume the caps to be passable.
I’m a bit on the lazy side, the usual thing to do is just replace all the caps.
