Hey Y'all, I just picked up a 1970's FET 500 HV. Anybody out there using one of these? What settings do you use? I use bass 8, body 9, and treble 2, on my FET 500 LV, but those settings ain't quite cuttin it for the high voltage model.
Thanks

David,
Try your Expand and Bite switches up,Bass 1/4 off wide open, body 1/4 off wide open, treble 9 or 10 Oclock, and reverb to suit you. You will probably want to alter this some. The master volume should run about half wide open at most as that is the way these amps were designed to run. Please let me know if I can be of any more help.

Thanks Harold, I'll give that a shot tomorrow. I messing with the bite switch earlier, but it didn't seem to make much difference. The amp sounds realy good. I only have two complaints and I feel like some minor repair would take care of that. It's got some hum, and I get a pop when I turn the power off. Seems like I saw a post that said bad filter caps could cause this. What do y'all think?
Thanks

David, These amps are very touchy about the reverb tank placement and the route the reverb wires are run. Try moving the wires around as much as you can with the amp on and see if you can get less hum. You might want to try moving the reverb tank also. I talked to Jim Evans and he said the wire routing and tank location were very important toward hum reduction. I've got mine working with little or no hum. Yes, these are great sounding amps and the hivolt FET transistors are as close as you'll get to a tube sound. Mr. Evans told me that these amps were the same circuit as his tube amps he use to make. His prototype of this amp actuallly had tube sockets in it with adaptors for the FETs. Please let me know if I can help in any way. By the way, what is the serial number of your amp. Mine is the sixteenth one he made. The number is; 8016.

Hey Harold!
Thanks for the info. I've been so busy the last couple of days that I haven't had a chance to try anything. Hopefully I can fool with it tonight when I get home. Mine is serial number 7045. I wonder how the serial number run on these?
I talked to a local amp tech last night and he seemed to think I might be on the right track with the filter caps. Of course, I'll try the simple stuff you mentioned first. You don't happen to know where I can get my hands on a schematic for this amp do ya?
Thanks
David
