Thanks for all the nice encouraging comments...I do build 2 meter amplifiers and the odd 70cm on request ...70cm is a lot harder to get efficiency...

I have a simple workshop and no special tools...I do everything by hand...I actually order the sheet metal cut to size for the amplifier cases...I use aluminum angle and pop rivets to do the final assembly..The cases take around a day and a half to complete as I have to cut out all the holes fror meters, sockets etc by hand...As I have been doing this for many years the job is routine to me...Fitting everything perfectly takes time and practice..Mum knowledge of electronics is rudimentry but I have taught myself through experience...Solid state leaves me cold..
