I obtained a Dentron MLA-2500B shortly before ARRL SS last fall, and proceeded to renovate it into operating condition (replaced filter caps and equalizing resistors, blew out dust etc.). When I fina

Hi John, It's tough to get an auto-tuner to work into a PA, because the inherent negative feedback and varying grid current affect the input impedance as drive level changes. It actually should have

The TS-450 has a reputation for being very finicky about VSWR plus a ATU with a less than ideal matching range. Many have disconnected this resistor in an attempt to obtain more output. In the initia

I have some experience with two mla-2500B's. One has the optional tuned input board - the other does not. I have not changed tubes with the tuned input one and it gets 1400+ keydown into a Heathkit d

The only way to get this much suds out is by exceeding the keydown rating of 350mA per anode/plate. Doing this abuses the cathode's emissive coating and puts it at risk of flaking. To see what happe
