Psycho Bass Guy | Re: Ampeg SVT opinions EI 7247's are really hit and miss; some are really noisy or microphonic. If they sound good, go with them. Watch for interstage distortion(usually some sort of oscillation) and you might want to consider a dual bias control, as there are really two different power sections running off of the existing bias control. Also be very aware, especially on the pre-Magnavox SVT's, that the circuit will vary to differing degrees from Magnavox's published schems (these are the most common). (Mine is a Selmer, and just try to pin that schem down!) Chances are (and this is highly dependent as to who owned the company when it was made i.e.-Ampeg, Selmer, or Magnavox, these are the only three who made the "real" SVT. All three carry the Ampeg name, but on the back grille of the amp, there will be a tag saying either: just "Ampeg" or "Ampeg, a division of the Selmer Company", or "Ampeg, a division of the Magnavox company") those caps need replacing. Even if the amp sounds fine, it will help it in terms of performance stability and consistency. Good luck as this beastie has a tendency to get really touchy sometimes, but when it works, it is the KING of all bass amps. PBG |
