i am working on 4 dynaco 400 amps. any one else?

i decided to move the 3 troublesome resistors off the boards ,onto 2 small circuit boards,2x3 on each

this should get the heat and weight off the boards and hopefully minimize intermittents.
res of course,1k,750,and 300 ohms.
small wirewound res are hard to find. im making up some with series or parallel units.

ive had these amps for 25+ yrs and hope to get all 4 running.

comments welcome
