I stopped by a local store to drop off some gear that I was selling on consignment, and when we were making room for my rack o'gear in the used section, I noticed the owner moving a familiar shape out of the way. Sure enough, it's a V-4B (with the baseball bat style switches). It has recently been retubed with JJ 7027 A's (I couldn't see the other tubes, but supposedly they're all new), and I eagerly asked to plug it in and try it out. Unfortunately, when we finally did plug it in, it hummed very loudly (regardless of volume setting). I could also hear the notes (which were very distorted, even at low volumes). The store owner thinks that it has bad capacitors (but this is being sold on consignment), and suggested that I either ask the seller to have it repaired, or offer a lower price and fix it myself. Cosmetically, it ain't too great. It's also missing the rear "screen." Any thoughts/ideas on whether or not this amp would be worth fixing? If so, any thoughts on what it is worth in its current condition? How about in a fully repaired condition? Thanks, Tom.
