Hi all.
I picked up four pro bel rack cards - basically for the Zero Field type Lundahl Transformers.
But having received them they look in very good condition.
But I can't find out what the card is.
I don't know if they are working or not and with the DIN41612 connector it's not easyy to follow the circuit.
Components seem fairly standard pro audio - NE5532 ; Pos and Neg 3 TO220 regs. Appears to have on board ac rectification and smoothing.
Would be a shame i think to take transformers off before I know what the board function is.
Any input appreciated. Thanks.
