Just picked this guy up the other day, I'm embarrassed to say how much (or how little!) I paid for it. 1969, 20 watts, 12" speaker, reverb tank, 2 Amperex EL84s, 4 Phillips 12AX7As. It still has the 2-prong cord, I'll be upgrading to a 3-prong soon and removing the 'death cap', etc. My amp tech told me to run it for a while and see how it sounded after about a half hour or so, let it 'cook' for a while. It def needs the pots cleaned, and I'm going to experiment with some other speakers, but it still sounds great. One thing I noticed - I shot the tubes right at the base with an infrared thermometer, the two EL84s and the V2 position 12AX7 were in the 200 degree range, the other three 12AX&s were around 90 degrees. They all were glowing about the same, and other than scratchy pots, the amp sounds fine. Should there be that much variance between the tube temps? Thanks in advance for any advice.
