Finishing up some odds & ends on the Riottenhouse RCM4 - Nothing dramatic, just the Amplifier Output Transistors . . . This Video turn into somewhat of a primer on Transistors - Chris

[@douglasosborn3378]

I always appreciate the attention to detail

Hi douglas: Thanks - I do tend to ramble on sometimes. . . - Chris

[@groovy1937]

Very informative as usual!

HI Groovy: Thanks - It got a little more involved than I had planned - Chris

My favourite transistors were 2N3055 for power supplys and a tip41A for driving.
Bc337 bc327 were handy too.

Hi zx8401ztv: Interesting, I don't think I have a favorite transistor - Chris

We used red to indicate PNP bipolar and P channel FET transistors. Don't know the origin but red is positive.

Hi atschiner: very cool to know - It seemed like a reasonable guess to me - Chris
