Yeah, I'm sorry about that.
These days, you pay a price if you want to be responsible and sensible, and repair your old electronic equipment. Most people simply throw it away and buy a new, cheap, poorly made replacement (unless they're wealthy enough to buy a properly made replacement). It may not last long, and it's false economy, but at least it has nice shiny metallic paint, right?
Back in my day (he says, pulling on his long white beard), there were lots of shops selling replacement parts. We even had a specialist shop called Wisemans (Wiseman Electric, actually) that had almost any IC you wanted to buy, individually foil-wrapped in a little plastic drawer in a big grid on the wall behind the counter. Old Mr. Wiseman would charge like a wounded bull, but he needed to, really, to keep the place going.
Wisemans was nearly unique in Wellington because the staff were electronics folks themseves, and could answer technical questions and give good advice. So the staff at other shops would send customers to Wisemans if they had difficult questions, and that wasted quite a bit of time.
In the mid to late 1990s the writing was on the wall as far as local specialist electronic components suppliers were concerned. Farnell and RS Components had a wider selection, a nice colour catalogue, and often, better prices. If you had Internet access, and could wait a day or two, they were a better choice than Wisemans. Courier companies were the big beneficiary.
Wisemans tried diversifying into security and spy equipment and other consumer products, then finally shut up shop, over ten years ago I think. Valve (toob) collectors all over New Zealand rejoiced! Cheap NOS ("new old stock") valves!
Nowadays a place like Wisemans would be totally impractical, given the sheer number and variety of electronic components available. It makes sense to have companies like Digi-Key and Mouser with huge warehouses on cheap land, supplying huge numbers of parts all around the world.
In this case, a thorough and careful inspection of the board earlier on could have identified those resistors, and you could have ordered their replacements along with other batches, to save on shipping costs (which are the biggest factor for small repairs now). That's a lesson learned I guess.
And you certainly are learning. Not much about electronic theory yet, but a lot about practical things like measuring components and soldering and desoldering. This is really important hands-on experience and you will get a lot of satisfaction when the repairs are complete. Whether it's worth the price is a decision only you can make, but I think it's too soon to say at the moment.
I'm going to try to sneak some theory into my explanations, since you're taking to this stuff pretty well and you obviously learn quickly. I hope you'll find it interesting. I can pretty much guarantee that you will
