Ok guys, the IIC+ HRG is done & I'll have it back home on Monday. I will report.
NEXT!!!! So I made the trip over & picked up that factory IIC+ DRG w/ the 105 PT last weekend!! I got a great price on it because there were some issues but fundamentally everything was working-ish. The reverb wasn't working, turns out he had the leads plugged in backwards. The Simul-Class switch wasn't producing any change to volume, turns out he had the EL34 in the middle slots & the 6L6 in the outer slots. (switch started working when I swapped the tubes back) I rolled the dice a little here hoping there isn't any transformer damage, but the amp was working fine otherwise. Also one of the tube sockets was dead, turns out there was one of those big resistors to it broken in half. The guts all look original except for the PI tube socket having been replaced. Owner says the amp has been in the closet for the last 20+ years. I crossed my fingers that all these problems are solvable by Mike B., beat him up on price a little & made the deal. I've already got a RMA from Rich & will be shipping it back to Petaluma next week for a full service.
So, now that the HRG is a IIC+, my next decision is do I keep the DRG a IIC+ or make it a ++? I really, really love all the tones this thing makes as-is. Getting a ++ would be cool because it's different & will have good investment value, just not sure I want to significantly change the character?? Talk about first world problems!
