OK,
I admit that I dont take on many service jobs anymore. I have a small selected clientele that I DO do work for. They are payers and dont quibble. After all "if it aint buggered, I dont change it ".
Most of the stuff I do is valved, but sometimes a furfy hybrid will sneak in. Its all band equipment, very little Hi-Fi.
I also dont do sand at all anymore, today it really IS complex with all the protection circuits requiring twice the components and complexity of the amp they protect.
When I said a simple design, it almost has the look of an application note from Motorola. The way the output stage is lined up for maximum current gain just looks like them for me.
The BC series transistors gives away the English part of the design. With decent components and a reasonably careful driver, they would sound OK, and would last for years.
The fact that they already have says that.
So when I repair stuff, I mostly charge in Australias currency. That is cartons of beer :-). ( One cartoon is $80, so you dont get many on the pension )
After all I am trying to unload most of my crap as I am starting to get into the fairly high numbers with age.
Valves that cost me fairly large amounts I at least try recover that, but passives I usually give away.
Thats just my take.
