I just missed the EL34 conversion on the se+. I bought an OD100 back in 2006. Many conversions later, it is now a PT100. I had mine for about a year and had it later converted to an SE+. At the time, SE+ still had 5881s and original transformer. People think the cleans are great on the current amps with EL34s and I have to say there are very few,if any, that compare to CAA. I do have to say the 5881s took cleans to another level. I did later convert to El34s. I then took it in to get the plexi transformer and just last year converted to a PT100. Same amp 6 years later and I have had nothing come close to pulling me away. Is it me or does that plexi tranny add some weight.
