I kinda sorta burned up my K12-G power transformer

[Frank Berry]

Most all power transformer ratings are based upon a half-wave rectifier (I learned this the hard way).
Since your amplifier uses a full wave bridge, the power transformer's B+ current rating would be about one-half.
Better to purchase a transformer which can deliver more B+ current than the original.

I'm not following your logic. Why would the rating for the new transformer need to exceed the rating for the original transformer? Wouldn't the original transformer's rating be based on the same conditions as the replacement transformer's? It seems like the idea replacement would be a transformer with the same rating.

Transformers can be purchased directly from S-5, they are $45 plus shipping

Edcor XPWR094-120

Secondary (output) Voltage 170V@250mA & 12V(6-0-6)@2.5A

Sorry to reopen an old thread but did this output trans. end up being a suitible replacement?

Assume you mean power transformer as opposed to output transformer. The recommended device should be a significant upgrade.

Ya I power transformer, it's been a long day. Thanks for the fast reply
