Hi, a while ago in a series of posts in this forum I have published several questions about the power peavey cs-800 c series (the old one, which has an aluminum front), and luckily, thanks to the answers, I have been solving little by little, every problem that the team has presented, which at one point considered it lost. My query this time relates to driver transistors and booster card transistors. I have obtained a peavey guide where there is official information regarding alternative spare parts that would work against the elements already discontinued. I need to know what kind of transistors this equipment originally used in the drivers and the booster card, to see if they are still valid, or, if they are discontinued, to look for the most suitable alternative. Beforehand thank you very much :)
