Hi all. I've been building amps like crazy these last couple of weeks. First up is my attempt at an SLO clone. I bought the preamp PCB from C3 and the rest of the parts are from stuff I had in storage. I bought a couple of Peavey Windsor heads a few years ago because they were dirt cheap. Didn't like the amp much so I gutted them both and used the chassis and cab for builds. One of these I used for the SLO build: This was a complicated build compared to the Plexi style amps I usually build, mainly because I had to look at pictures on the internet on all the stuff that goes into this build that is not incorporated on the PCB. I guess I did it right because it plays and considering how much gain this amp has, it is relatively hum free. Personally, I would change the location of the "normal/overdrive" switch. If I could do it over, I think I would put that switch between and under both "gain" controls and have the toggle switch from left for "normal" to right for "overdrive". The other two switches seem to only work in "normal" mode. As you can tell, I've never played around with one of these amps, so I kind of went blindly into this project. For the PT, I used a RCA transformer from a vacuum tube type RCA television. These old TV transformers make great PTs for tube amps; they are beefy transformers. I used the Windsor OT for the time being but I will probably switch it out for something a lot better quality when I have more disposable funds. The choke is rated at 7H @ 70ma. I don't know why they spec a 200ma choke for these amps because the most current that will go through the choke is around 60ma as long as 6L6 type tubes are used. With EL34s current through the choke will be about double. Most of the other parts are what I had lying around; everything else is to spec on the schematic even though it may not look like it on this build. The face plate is a work in progress. I need to print out all the names for each control. I put the effects loop on the front panel since that is where the 2 jacks were for the Windsor. By the way, does anyone have one extra Peavey Windsor knob that they are willing to part with? I need one more knob for this amp. I am willing to pay for the knob plus shipping if anyone can help me out.
