Hi,
I'm new to this forum - thanks for letting me come aboard!! A few months back I acquired a 41-788 and have just started looking into it. First off - the speaker was missing but I have an equivalent electrodynamic speaker that I can use to get it up and running.
My first concern is the e-caps.... there are 2 cans - one is a multisection labelled with values of 40uF, 5uF and 5uF. For the life of me, I can find only the 40 and one 5 referenced on the schematic - where's the other 5 ???
The other can is covered with silvered paper - for insulation I suppose - and I can see no values on it. I assume it's the 16uF shown on the schematic - but it has 3 terminals. Does anyone know how this cap is set up???
And, finally, I have a 10" PM speaker I will eventually use in this radio. What is the best way to allow for the lack of a field coil - should I simply sub in a power resistor and up the value of the filters caps - or do I need a choke too.... and what values would I be looking at trying to find???
Thanks.....
