Hi Mark, It's a Fujitsu and pretty good for the small price I paid for it. I haven't studied it too much yet so maybe you can change pixel size easily enough.
Going on what you said I went through a phase of very heavy theory using a 1960 HAM radio construction book. This had lots of circuits with valves and a fair bit of maths and radio science. I don't regret the late nights racking my brains with a calculator and going through circuits but finally I realised I had developed no actual hands-on engineering skills at all. I could talk shop or even maybe impress people with some theory but the truth was, as a practical repairman, I wasn't that good. I also understood that experts such as Chas Miller who wrote one of my books has actively dabbled with vintage radios for many years and learned through blood, sweat and tears. So, I put theory on hold for a little while and am doing my best to learn actual repair. I am learning, yes, from these cassette players.
Also I'd like to add I came to understand valves can be pretty dangerous for beginners. Working on transistor vintage radios or cassette players is a safe way to get more used to using Ohms Law. Doing similar tests as a novice on a 260 volts VAC valve radio isn't for the faint of heart.
Anyway thanks for the positive feedback. That auto-eject mechanism has really given me headaches. I tend to be a bit slow taking in new designs but I think it's gradually becoming clearer.
