Hello Cable Guy,
Yeah I really don't know at this point, but I was the cause.
I say this because I was trying to key an external box that needed a PTT to RCA
in order to key the box. I was just testing the radio and decided to key the box by just grounding out the RCA to bring in the relay. Well the RCA jack was not even mounted, meaning it was just balancing on the bench while I was trying to short it out while keying the mic. Yeah I know...It had disconnected and then reconnected during transmit, and the next thing I know the finals had blown.
As for the 10k resistor, I don't think it had gotten shorted or open, but I did see it on the schematic.
It won't hurt to check it.
I really need to be able to adjust the BIAS regardless, so I will have to try to find those final pots somewhere online.
Does anyone know where to purchase them? And what are their values? Also I think I read somewhere they should be at least a 1/2 a watt.
Actually does anyone have a better source where to get parts for this radio besides RF Parts, Mouser, Newark Electronics or ???
Thank you all who have chimed in to help. I will be checking on more voltages that the service manual recommends. Of course if I find anything I will certainly post it here.
And again Cable Guy, Thank you for helping. I think it was you who mentioned about changing out the old caps. I will eventually be doing that as well. I think I had counted like 42 caps on the main board, so that will be a slow process.
Again Thank you.
RF Krazy
