All of that era head should be re-capped since they are older than 20 yrs old. The caps will probably have to use substitutes since the 150uF@150 volt is not available. I put 200@150(I think) in mine and all is fine. The voltage rating can go as high as you want but the uF should be as close as you can get and NEVER lower. A little higher doesn't hurt. As far as tubes, I am using the JJ's right now and haven't had any trouble with them. They sound great but we will have to discuss longevity after they have been in for a year or so. Don't forget tat the bias on a MM tube driver amp is around 14-15 mA PER TUBE. The bias directions for the SS driver is differant as it is a wierd cathode bias type amp with TOTALLY different settings. Mike.
