Vintage HiFi repairs - newb and want to learn

Hi team - looking to learn about electronics from the ground up, so I can get enough knowledge/skills to repair vintage hifi - amps, receivers, stereograms, etc.

Not sure where to start, and it was suggested to me to post here and see if anyone else is interested in something similar. So this is me doing that.

Will come down to next Tuesday Open Night to check it out, but wanted to say gday first!

Hi TJ,
Right up my alley after long career in electronics and IT. Happy to meet up with you on most Tuesday nights (not 8 May).

I’ve got some intro to electronics classes ready to go, but I’ve been holding off as I haven’t properly organised the hands-on lab exercises that run after the class.

If you are in on a Tuesday, I can hand you my reference books that I’ve been using to make the classes or have a look over a circuit/schematic of your equipment for what it’s worth.


While I haven’t had a lot to do with specific vintage stuff, the good news is larger components in vintage stuff are very easy to work with - and you can often immediately see what the issues are (ie blown or swollen caps, smoked resistors, etc). I’ve built and modified a few modern tube amps, and it’s pretty hard to go wrong providing you have the relevant dexterous skills and don’t forget how stuff was originally wired/plugged together.

In terms of prerequisite knowledge, the main thing I’d be recommending you learn how to do is interpret a circuit diagram and the basics of electrical theory (resistance, capacitance, inductance, current, voltage, power). There’s no IC stuff on the majority of vintage gear, which greatly simplifies things.

That’d be great.

I have two problems that I am looking at currently - an american amp that needs a voltage step down and an old AKAI amp (Aus) that’s dead.

Obvs won’t be ready to look at this until i learn the basics, but would be great to come in on Tuesday and chat :smiley:

This sounds encouraging :smiley: Would love to chat with you about this.
