If you decide to overhaul it.
Have fun resoldering the entire unit due to poor solder joints.
You will have to desolder, mechanically clean, and resolder EVERY single joint in the whole unit.
And theres only a few relays that will need replacing. I mean, All of them.
I did this one back in 2016.

I had to rebuild this one due to a previous 'repairer' doing a half assed job.
Apparently, burning a hole into the sealed relay tops with a soldering iron to spray in some chemical is preferred to replacing the relays.
And lets ignore the foam and glue that goes conductive too.

From the first pic somewhere along the line it appears the decision was made to just eliminate the capacitors discussed here.
Or looking at the differences in the parts count on the top board, I'd say some kind of model differences.
It would be interesting to see the front and back panel of the device under question.

Interesting. This is luxman board. Just look at the markings on these styrene caps. 102J, Just like on c90 polystyrene caps.
102j....
just like every other ceramic, monolithic, polyester, polypropylene, polystyrene, tantalum, etc etc etc.
could it possibly be that 102j is no more than a universal way of describing the actual capacitance of any capacitor that is designed to be a certain capacitance ????
wow.
maybe the whole idea of using Farads, Ohms, Henries, Volts, Amps to define an international measurement standard is fundamentally flawed.

102J = 1nF 5%

Please, please tell me this is sarcasm and I just missed it due to lack of caffeine...

Andy, the markings have nothing to do with the dielectric. See this... https://www.budgetronics.eu/en/capacitor-codes/c-15
The sarcasm is very strong in this one 🙂
But I'm fairly certain the last 45 years of my life playing in this field were nothing more than a fabrication devised by the agent smiths to keep me in the matrix.
Bazinga 😛
Who here remembers the days when the value of tantalums were done in colour bands with dots ?
And the hysteria when you get something other than 10% carbon film resistors.
Ohhhhh the utter joy when you could get small polypropylene caps without going on a global scavenger hunt...
ah those were the days...
Youngens, tell em this and they wont believe you.

I'm glad to hear your sarcasm-fu is so strong!
I've got a box of probably 3-4K of the tantalums with the dots - don't need or want them but just can't bring myself to throw away perfectly good components 🙄
But, old habits die hard - in spite of the availability of Mouser, DigiKey and such (and available funds!) I still am incapable of throwing any electronics away without scavenging for usable parts.

A small pedantic point - we don't use those, we use farads, ohms, henries, volts and amperes. Capitals are only for the people the units were named after, or the one-letter versions of the units. After all we don't say Miles and Metres and Yards and Seconds and Hours....
There's kind of a odd case with degrees Celcius (which is officially capital C), but we should be using kelvins anyway! I am in two minds about henrys v. henries, but saying henrys would imply using luxs which seems wrong, but irregular plurals doesn't seem very international...
