Stevem's comment on the drive tube's plate resistors is spot on - I haven't yet found one to be intermittent or noisy, but occasionally I get an amp from this series that has no output drive or half the waveform missing and in these cases it's usually an open plate R in the drive department.All BIAS Amp Series hardwares (BIAS MINI Guitar/Bass and BIAS Head/Rack) come with a free BIAS Amp2 Pro Desktop license. So have a very close look at those problematic 5W R's and their connections, a loose one would cause the crackling problem you describe.
After looking everywhere else, that's exactly where the problem was! One of the 5W leads simply cracked in two making intermittent contact. A year previously I had replaced the voltage dropping 5W resistors so I figured "that can't be the problem". You can adjust that but it's not likely the cause or result of your crackling racket.Ĭouple weeks ago I had a similar amp with a similar problem. Other way around - drawing too much current from the HV supply will increase ripple, and you said output tubes are running hot = overcurrent. Is this normal? The ripple is consistent and does not seem to follow the crackling noise at all, but the tubes seem to be getting abnormally hot. BungleSim wrote:I did measure 7.2V of ripple on the B+.
