The latest amp I've bought has handle troubles. One is missing anyway but both have chewed out their screw holes in the case. Case is nasty particle board, but I can't change that... I think the handles are under engineered - just 4 screws for each for a heavy, old-school 200W valve amp. Does anyone know if the original style handles are still available - preferably in a bigger size so I can screw into new wood? Existing screwholes are 113mm between horizontal centres and 90mm between vertical centres. Or should I paint these black and fit them nicely? They have more screw holes. The case is in hardly in mint original condition - someone has already cut a round hole into the top for extra ventilation/place to spill beer into.
