Anybody here have any thoughts of trying to use a 5K PP OPT that is rated for 75mA per side with this schematic? I recently foung a pair of Chicago STD potted OPTs with this rating. They appear to be of high quality and I would like to use them. I understand the general current through the 2A3 is about 60mA. This would be close to the limit but I rarely abuse my system. Also, what about running the bias point a tad bit cooler? Maybe up the cathode resistor to 800-880R?
