I'm hoping one of the TB bass gurus can point me in the right direction. I have an Ashdown Little Bastard, about 1 year old. Great little amp, except that shortly after getting it it would pop and then cut out while it was warming up. After it warmed up (~5 min), there was no problem. I e-mailed Ashdown customer service about it, but got no reply. (Can't say I'm at all impressed with their customer service at this point...) Anyway, the cutting out has gotten progressively worse, now happening even after amp is fully warmed up. I'm not pushing the amp at all (practice volume only). I tried plugging into the effects return, but get the same popping/cutting out. Here is an excerpt from a Tom Bowlus (Bass Gear mag) review: "One 12AX7 (ECC83) drives the series effects loop with one valve stage, and drives the passive (and interactive) tone controls with the other stage. A second 12AX7 drives the output section, and phase splitting is handled by a fully floating selfbalancing paraphrase inverter based around a 12AT7 (ECC82). The DI is taken from a balanced winding on the output transformer, and as such, it is decidedly “post EQ.” So, based on my extremely limited knowledge about tube amps, it looks like it is pointing to one of the power tubes ( 4 x EL84)? Should I try the tapping with a wooden stick (the power tubes are fairly accessible)? Or am I completely misguided? Thanks in advance for any help/suggestions! EDIT: I called it an Ampeg in the title. Wishful thinking I guess.
