Re: BEC Capacitors
There is no way of knowing. It depends on whether they operated a careful stores policy of keeping batches together and using oldest first. If they just tipped new arrivals loose into a bin, old ones could hide in bottom corners for some appreciable time.
Not all capacitors will have been bought from the same makers, not all will be date-stamped. David |
Re: BEC Capacitors
Hi Bob.
With the huge amount of DAC90A’s produced, I would imagine that those components would have been manufactured, delivered and on the radios production line in a very short space of time. It seems that a large proportion of DAC90 production used these BEC (British Electrolytic Capacitors) in this position. ......And they’ve proved to be a good quality, long lived item, too! Cheers.

Re: BEC Capacitors
Hi David all the DAC90A that i have seen have had BEC capacitors apart from my 1950 DAC90A chassis it has a Radio Spares Capacitor with no date on it must have been replaced in the 70s as the wiring to it had been changed as well . Hi Simon Bush must of had a supply contract with BEC for smoothing Capacitor as well as TOC for the waxies you are right about BEC been good Quality and long lived kind regards Bob

Re: BEC Capacitors
As shown here my DAC90A has a date of 1955.
