Hi all,
An acquaintance of mine purchased an Operatic Model 140 wth the promise it worked - it doesn't.
The reason seems obvious - the power supply (for some unknown reason) has been dismantled. I can have a fairly good guess on how it goes together, but I hate to guess.
The case is marked Model 140 but the chassis is marked Model C62RC, so may have been manufactured by an alternate company.
The output transformer is marked 10 APR 1958 and the speaker 25 FEB 1957. The amplifier uses 6AQ5's in push-pull mode. It probably used a 6V4/EZ80 as a rectifier.
Does anyone have a circuit diagram for this radiogram or a suggestion as to where I might be able to get one?
Regards,
DaveH.
