I have an SB1000 and I bought a Chinese 3-500G tube. Worked great for
awhile, about 40 hours... then one day..I came in and turned the amp on to
warm up, and both 15 amp fuses immediately blew. I have it connected to the
120V
wall socket. I cautiously unplugged the amp, removed the tube, replaced
the fuses, and put everything back together. I turned the amp on and it
performs great.....the pwr supply and fan run and I have about 3200 Volts.
So I put the tube back in and blam!...it blows the breakers. How can I
test this tube, and any other ideas before I send the tube back to AES.
thanks.Greg.
