What is the Sony p/n for the "G" board for this model? (I'd be interesting
to see what Tritronics cost on the part is)
Also, When set comes back in, I will install the 2SC4834"P"s so they willl
run cooler and also the VDR in P/S and all the electrolytics near the Horiz
drive transformer. Since I am at home and not at the shop, I only recall (1)
VDR in the P/S. Are there (2) VDR's in this model? I do recall in other
models as many as (3) but only recall (1) in this model. I'll research more
when I get to the shop.
