I would think that sucking hot air out of the back of the radio would crete a more stable temperature environment inside the radio across the changes in heat generated from RX to TX. With (theoretically) the most stable temps being the farthest away from the final cage. What's in the opposite corner of the transmitter from the final cage? The PTO! Seems to me that cooling the radio would reduce drift. Aside from that, it's a scientific fact that ANY electronic component (not just toobs) will last longer when run cooler. I would prefer to err on the side of component life. 73 -Jim -- Ham Radio NU0C TR7/RV7, TR6/RV6, T4XC/R4C, L4B, NCL2000, SB104A, R390A, GT550A/RV550A, HyGain 3750, IBM PS/2 - all vintage, all the time!
