    Is this a TT-4 Custom? The hardware looks like ADC-era, but the peculiarities of the stop list and the console layout do not look like any ADC stock model I'm aware of. The stated need to replace "sound cards" for individual stops also seemingly lead in this direction.

    Probably MDS. Later ADC and MDS organs were somewhat similar. Slim pickin's in on the manual stops, though. Quite a basic organ w/o many frills.

    Way too many organs to list, but I do have 5 Allens:
    • MOS-2 Model 505-B / ADC-4300-DK / ADC-5400 / ADC-6000 (Symphony) / ADC-8000DKC
    • Lowrey Heritage (DSO-1)
    • 9 Pump Organs, 1 Pipe Organ & 4 Pianos

    It looks like a late era ADC custom, which might use the TT-4 system--not sure of the particulars of Allen's custom nomenclature.

    I think this is similar in design approach to the Classic I discussed on the forum previously--almost one voice per card, or at least very few voices, and likely stunning results. I doubt it is an MDS because the original church (Grace Presbyterian Church in Walnut Creek CA) has a Quantum 370 per the Nor Cal dealer's site, and I think it more likely to replace an ADC era custom than an MDS Custom based on when the Quantum series came into being.

    Also, no console controller, and surely an MDS custom would have that plus indicators.

    I'll put my bet on it being a custom ADC TT-4 instrument. He says it was originally designed for 8-12 speakers, now reduced to two. I don't think an MDS with so few stops would have had that many audio channels. But that does better match the number of amps and speakers John found when he serviced that ADC TT-4 instrument. When this one got moved from the church to a home one wonders what happened to the original amps and speakers.

    So the ad says that six of the sound cards are bad, they mean TT-4 cards, I presume. The samples are on EPROMs, so you can swap the boards around freely, just change the EPROMs.

    For a no-cost fix one could sacrifice six of the stops. I can see six that I would be happy to live without. (All three of the 16' manual stops, and three of the pedal stops, since it appears to have an abundance.)

    And there could actually be nothing wrong with those six boards anyway. I have to wonder if the owner or tech has tried the "Vaseline" treatment on the cage sockets or EPROMs. It could also be a bad USAP card in one of the cages, or a problem with the ADC mixer board. Or the person who re-configured it for just two channels may have mis-wired it some way.

    These TT-4 voices are absolutely incredible, and if you have the room to do it, a two-cage organ can be expanded to 16 audio channels. I only wish it weren't so far away!

    (My hoarding instincts are kicking in... Truth is, I don't have room for anything else in the shop, and I don't need another organ of any kind!)
