Reverb tank for Kustom 50

[mac1amps]

Anyone out there know what the correct specs are [or where I might find them] on a reverb spring tray for a Kustom 50 combo? The schematics I've tracked down for these don't say much........anyone?

If this is a tuck and roll combo with the reverb tank mounted inside the head, 4FB2A1A .

If the tank is mounted in the speaker cab, then the mount position code will be different.

FWIW, I ordered a 4FB2C1A (same as 4FB2A1A except for slightly different grounding), but unfortunately it wouldn't work with this model Kustom. Out of desperation, I tried it with a couple of older spring trays I had lying around (yah, I know, why didn't I try that before?), and it ended up working with a tray that had come out of an old Vox with a lower input impedance (around 150 Ohms, or a D.C. resistance of about 25 Ohms, as opposed to 1500 Ohms/ 200 Ohms D.C.).........oh well.Thanks though.

Did you ground the input on the new tank? Kustom, like Vox used a drive cable that had no ground connection to avoid a ground loop.
