I have been using PS-2A with both my 65 Deluxe Reverb and 66 Super Reverb with good effect. However, my amp tech tells my using an “attenuator” with these olds amps can damage the output transformer. I believe that because the PS-2A is a reactive load high heat is not generated in the output circuit as it would be with and ordinary attenuator and the risk of damage is not greater than that of ordinary operation as long as impedances are properly matched. Please settle a controversy for me or tell me a safe way I can continue to employ the PS-2A with these fine old amps. Thank you.
Hello and welcome to the forum! Yes, our patented reactive load is much more friendly to your vintage amp’s output transformers than a straight resistive load, and sounds and feels much better as well. But the more significant reason power attenuators have a reputation for potentially damaging amps OTs is because players tend to run the amplifiers at too high of an output level, being lulled in to a false sense of security by the power attenuator lowering the volume to comfortable levels, but while pushing the limits of the amplifier’s components and power tubes which puts excessive strain on the amp’s output transformer, and in some cases the power transformer as well. The best approach is to dial in the tone and feel you like best with your amp, then engage the Power Station and dial back the volume to where it works for you. This way you are probably not running your amps at full volume and thus you will not have to worry about damaging them in any way. The louder you run your amps, the more accelerated the wear is on the power tubes. It’s always good practice to keep your amps and power tubes well maintained for optimum results and reliability. Hope that helps. Cheers! Gil
