Klaus Schulz.....The Rhodes Elegy
Yup, excellent little amplifier. Driving the JBL Millenniums. This will work well in the active system if the gain structure is close enough to the WOPLs.
The A30 Professional version of this is now listed on eBay. Poor condition and ridiculously way over priced.

According to my calculations it'll do 600 watts per channel into 1.5 ohms. Service manual says it should output 31 Vrms before distortion rises. So using the Watts Law AC equation, 30x30 divided by 1.5= 600 watts. There's probably a mountain of factors that I don't understand that wouldn't allow this. 
On a serious note, been running the amp continuously all day playing Klaus Schulze FLAC files because his music has so much dynamic range. It just keeps getting better and better as those new caps settle or burn in. Just another thing I don't understand and probably never will as I can't see it or touch it. Has to do with aluminum oxide forming on the caps internal surfaces from the little I've read. I believe it's a real effect, and not imagination.

Really no upgrades that I'm aware of other than doing a full recap, inspection of all boards and joints, get all the flux off the boards.
Mine has sat unused since I gave it a little burn in time.
I do want to add a IEC socket to it.
Eventually it'll do tweeter duty on a 4-way amp/active crossover system.

Someone is selling a repair kit
https://www.ebay.com/itm/3729357028...eFA17eo8+g+9MMmJJhTvUg0EXF|tkp:Bk9SR4LT-dTqYg
Does it make sense to replace the transistors and resistors, or the original are fine ?

If it's working, just get it recapped. This was built during the era when Pioneer owned PL. Better parts were used( this can be argued ). Uses the same output transistors that Pioneers flagship receivers used at this time period.

Did you do any comparison with his siblings ?
