When I worked in the shop and we started to see Fender, Marshall and the likes building tube amps with the power tubes mounted on pc boards we went "whoaaa....this can not be a good thing." The heat from these tubes is going to be a problem in the long run with weakening the pc boards over time. Many were trying to mount the tubes on the horizontal to try and minimize this but regardless...there was no way they were going to be as tuff as the old hand wired ones.
Back in the mid seventies I had a Fender Brownface BandMaster head and we were getting set up for a gig. Somebody did me the favor to drop the head from ten feet high onto a tiled floor and one of the power tubes popped out and rolled across the floor. Popped the tube back in and played the gig with no problems.
Love the old hand wired amps
