tried another 6HS5 reg tube, a little better, with HV fully CCW I could just get it to 25kv but that is with normal brightness on the screen, when I turned it down the HV went back up to 27kv. I am sure there is an issue I have just been avoiding pull the chassis, its a real dusty mess.
I left the SS amp on all night (by accident) AM has a lot of rushing sound now between channels. Was not doing that before. I will try again at a differnt time of day to see if I can rule out RFI. I fear that RF transistor may be going bad, in which case I need to figure out whats going on (why the 1st on went and now this one. I can pull it and check on my transistor tester. I should have done that in the 1st place on the replacement to base line it.
