I have not tried them and do not think I even own one. If I do own one it would be a gift from Gatekeeper. I am not one to chase after max power out of a signal device. So the idea of the 2879C from HG has zero appeal to me since I own 16 or so of the their regular 2879 marked product.


I am the type of guy that would build a 4 transistor device and proceed to run it at 2 transistor output levels on a heat sink large enough for an 8 transistor setup.


Build an 8 transistor amp and run it at 4 transistor output levels again with 2x the heat sink others would use.


Once in a great while tickle the electro-pixies just to have a some fun responsibly. So pushing harder on a part from a company  with questionable quality control for more watts when I could just add more transistors makes no sense to me at all. Either way the volts and amps needed is so close tot he same for the added power compared to tossing another pair in inline it is false economy. HG's do not like running more than 15V reliably with out random popping it is not like the glory day of Toshiba 2879's that you could easily push to 21-24 volts and expect them to hold! Even the TRW and MOT transistors could largely be volted and expected to survive longer than they should have. If you can not push the volts up than the current requirement will be much higher and higher current means a lot more heat!!


The only people I know that really like the 2879C's tend to be people that run amps like idiots so keydown, drunk agitators and bowl type people not running tubes or LDMOS etc....They do not seem to offer much to the average user that uses an amp for actual rag chewing two way intelligent communication with other human beings. The builders that push them tend to cater to that sort of customer base and the meter-baters(sp) did I spell that right? Heard it said on youtube but never seen it in print!
