Yes... those tubes are pretty exposed. I see that some have devised grid type guards that will allow ventilation. I think I'll do that. I was a bit paranoid about fooling around too much around the tube retainers after reading that the caps hold a charge for some time and I could be shocked. I'm new to tube amps. It looks like all the electronics are under a metal cover so do you think I can still get shocked digging around the tubes if I don't go under the cover??
Thanks for responding. Fred
