[Axeman2009]

Hi,
Does anyone have any experience with this website?

I am thinking about buying a Crate BV60H head and want to overhaul it with new higher voltage power supply caps and higher voltage "wire wound"? resistors. I do have experience installing a 3 tube mod into a MP-1 Preamp already, and it works perfectly thank you very much! lol
I would be interested in improving the tone,gain and in improving the reliability and making sure its the best it can be....
Thanks for any help/input! (especially thanks to Enzo for the schem's)

Higher voltage caps may offer a little extra margin of longevity if they fit. Getting a higher quality cap would be more important. Higher (did you mean wattage?) screen resistors may not be neccessary, if they use 5 watters already. Not sure. I've worked on a couple of those amps. biggest problem is the input jacks getting loose from use.
