Cleaned relay, replaced cap bank. Installed new meter board. Amp seems to be working fine now. Tubes don't glow with just a small single final radio like before. Actually does about 30w pep more than before replacement. Cleaned and oiled fan. Amp seems to be running fine now. Nice little amp for what it is.
