We've a very sick AMS DMX 15-80 delay that i'm trying to fix. We think its an early version (ex-bbc) and doesn't have some of the features of the later models.
Initially we thought it was missing cards but now believe it isnt, so its worth fixing.
A schematic would be very useful!
The chaps at AMS have been very helpful offering advice and possible solutions but unfortunately they can't give out the circuit .
Before i can get anywhere i need to replace the power transformer as there's a short on one of the secondaries.
Can anyone tell me the specs required ?
This is an old model with a linear supply, not the switcher model btw.
Also in this DMX the fan is wired straight to the mains via a resistor so i won't need the 150vac secondary.
I think i need 1x 9vac, 2x 18vac and 1x 15vac but that would mean three transformers!
Maybe if i could get a peek at the psu schematic it would all become clear.
Anyway some pictures for the gear freaks.
