My new HBE module is unusable with the gain past noon. I get a ton of squealing feedback then. In comparison I also have the SLO and BE and both those modules are quiet even with gain at 3 o'clock.
I replaced the pre-amp tubes in the HBE...no change. Probably needs to be sent back to Synergy.
Anyone else experience this with a high gain module?

OK I take back blaming the HBE module. There is nothing wrong with it.
After more detailed troubleshooting and the problem getting more consistent (less intermittent), worse, and affecting all the modules in the amp now it's the FX loop. After unplugging the loop, problem gone. Probably the FX loop buffer tube. Swapping in a new tube is next on my list.
On another note I did get quick reply from Boutique Amps Distribution tech support. So that's a good thing.
