Anyone have a 90s SWR Basic Black?

Good question, it's Mercury Magnetics. It seemed to me to be the original one, given the special voltages for this amp...?
I dont k'ow?!?

Maybe they made some export parts for SWR, but they also made a lot of replacement parts for the service industry.

Well, there's some damage after measuring the components. I don't know if it's worth it and if there isn't something else that's been damaged. What do you think, given that the two Sanken 2SC3164s are impossible to find or there's too much risk of them being fake? Since the original parts are unavailable, I'd like to switch to robust and inexpensive equivalents. Here's what I'm thinking of looking for:
1. For the Sanken (Power) chips: 2SC2922s (these are the standard replacements). If they're too expensive, the MJL21194 is a workhorse that costs around €5-6, but you'll have to modify the mounting a bit because the package is smaller.

2. For the trio of drivers:

The 2SA1837 (to replace the two A1668s).

The 2SC4793 (to replace the C4382).

3. For the orange diodes: Get 1N4148s. It's the most common component in the world, it costs a few cents.

With all of the other damage and poor work, I wouldn't bother. It’s not worth the cost of fixing it correctly IMO.

Yes, the boomer is dead too, so it's useless. Thanks anyway.
