Jim;

Regarding tube break in time; I wanted to let you know that the matched quad of EH 7591's arrived today along with the Russian K40 pio caps, and 200k grid resistors. The Fisher 500c sounds stupendous.......Immediately!

The power transformer was only slightly warm, and the output transformers were barley warm after a hour and a half of spirited playing.

Here are a couple of before and after pics. Those k40 caps are H-U-G-E compared to the tiny Illinois caps they replaced.

Thanks for the great parts and fast service!
