Dan: When I changed the tubes in my 811H, I noticed that the horseshoe shaped clamps that tension the individual pins on the bottom of the tube sockets were quite fragile. In fact, several had broken off and were shorting out to the case and I was getting intermittent arcing. The fit between the bottom of the tube socket and the case is tight. I would check there first for a short. Paul (WL7PC) Dan wrote: You guys have had the answer everytime so far. I bought a 2nd hand Ameritron 811H amp. It has worked very well exept .. at first start up serveral weeks ago.. after it had been stored when i first turned it on it arec at the vents 9right side) switched it off.. long story short after a few turn ons and off it work great.. I get good ooutpit and great reports. Well over the past few weeks once in a while (only when I turn it on) I woud get an arc same place. after it has been on and after serveral times on and off during the day it would be fine great output and no arc even when switched back on .. seemed like only would do it after it had been off all night and then only sometimes.. I have remoed and check for any signs of arc etc never found anythign.. Well until today.. I switched it on.. and again a little arc that was visable at the vents.. and quickly this time a loud pop.
