Is the GAT / ET5 hard on tubes?

Wow, those things really eat tubes. They should have had a way to lower the filament voltage down to 6.1V or so. The old Dynaco preamps came with Telefunken tubes from the factory. Yea, I know, not in the same league as A CJ preamp but they ran the filaments a little low and most of these can be found with the original tube compliment still in them. Heck, when I found my crusty MC40 monoblocks they still had most of the original tubes.
CJ should come up with a solution and fix all of these at no charge. A lot of coin for a flawed design.
