There is a very small amount of air movement through my inverter cabinet, turns out this was enough to keep the 7805 regulator in the R6 PCB only warm to touch. On the bench, the 3 terminal 7805 5v reg is now quite warm, however these things can take some serious heat and it should be fine, but again, a small heatsink keeps it much cooler. The KA7805 4 pin reg in the new R7 board has a tiny heatsink, and runs slightly warm on the bench.
