Thank's for the heads up. Heyboer said they can build the transformer for $225.

GK 800RB power transformer?

It's a Christmas Miracle!!!
I found a local guy that sold me a working replacement GK transformer for a fraction of what a company will make one.
I am shocked! (Not literally.)
My Holiday just got a lot happier!

BTW, I got the transformer and extra parts for $66.
Now to bring this beast back to life.

I just got a reply from Pacific Transformer. It took them a while to get back to me. They are quoting me $180 to buld me a replacement transformer.
Of course I will go with the transformer I bought. I am posting this in case someone needs a transformer built and comes across this thread.

It all looks very stock, but I don't think it is the OEM transformer. I'm wondering how much the amplifier is starving being low on the rails by almost 10 V did a bias check everything seems perfect with the bias and DC offset. From reading post in the group and looking at the schematics it looks like they're supposed to be 85 V rails someone prior to me has installed on new capacitors and everything. The 100 W amplifier rails are around 56 which I believe is about right?

When an am's been worked on before, there is no way to know what is right and what isn't unless you are very experienced with that model. It makes things very difficult. The lower voltage will reduce the power on the larger amp channel. If it can provide enough current without too much sag, it may work "ok enough", but this is why I always recommend sticking with original factory parts.
For example, with the Genz Benz and Mesa Subway amps, I have seen thousands and worked on these specific models for many years. I also designed them and wrote all the service documentation so I know exactly what they are supposed to look like and how they should perform. It makes servicing correctly a piece of cake.
