[Kenwood] TS511 blowing fuses

I highly suspect the electrolytics in the power supply. I use to have 
one of those rigs. A great unit but also a hybrid of output driver tubes 
and the rest solid state. The unit is old enough to definitely have 
electrolytics going bad. I just got finished with replacing the 
electrolytics in my Johnson Viking Valiant II.

I found the replacements at a very reasonable cost from 
www.tubeaudiosupply.com on Ebay.

P.S.
Nice transceiver. Wish I still had mine. Nice 500 ssb unit using tv 
sweep tubes in the output. The in country Japanese version was the TS510 
which only ran 100 watts.
