re: TK-140U and TK140X

I just found this website and for a guy like me it's GREAT!

First about the Kenwood TK140u. This was a cost-reduced version of the TK140X that came out a year or two before. Most notable its the shrinking of the physical size and heat-sinking of the transistors that drive the output transistors. I didn't see any reference to the TK140X here, so when I get time, I'll have to submit info - I have a factory manual and owner's manual on it. I'll have to check some other manuals I have too to see if this site has them. The TK140X I bought new and still have and it's an excellent receiver.
FYI: From December 1966 to June 1969, I worked in a repair shop for a company that had two, very small, corner stores selling component stereos, with a total of about 15 employees. From late 1967 to June 1969 I was their only repair guy, and I wass part time, while going to school. The company was called Sound of the Northwest when I started there, and while there, name changed to Sound of Music, and today the same company is called Best Buy!
I'm retired now after many years of designing medical products and old audio stuff is one of my hobbies.
What I do need is a source for the pilot light bulbs - they look like a 3AG fuse - need some for a couple Marantz receivers I have too - anyone know where I can get these?
