Relax
All o.K. out there? Or all under the headphones - completely drifted away by the wonderful music....
Great work Dirk!
Yes ok , I have fundelic time with Genelec 10-30 A https://assets.ctfassets.net/4zjnzn...0c4299aa8404be6a62080a5aa/1030A_datasheet.pdf
Repair for friend of my friend who work in professional audio music production, doing recordings and masterings albums. This studio monitors was made in Finland and are 25 years old. All electrolitics capacitors are leaky, one "exploded" and one CMS resistor was in
hybrid IC STK amplifier " brick" is gone 
Need find some new old stock chip by

Hello soundhappy,
interesting restoring-project!
I like 2-way-monitor- loudspeakers. Didn't know the Genelec active monitor.The spl-curve looks really good. Especially for an 'older' design. -3dB-point
seems to be around 40-50Hz - pretty good for a mid-woofer of ca. 170mm diameter. No extreme bumps in the spl-curve. And an active loudspeker..I can see the 'killed' caps. Also some smd-resistors which seem to have become pretty hot. Also some traces on the pcb seem to have seen a lot of heat.... Those are chip-amplifiers. Are they still available?
Have success with this project. I am sure those genelecs can sound really nice! I think they are pretty 'neutral' as most monitor - loudspeakers used for checking / monitoring recordings.

Super PAC work
Yes is sorta older version technology hybrid chip amp STK module from 90´s. Not available new but today Genelec produce updated versions.
Tested one speaker who work perfectly now with young caps. This is audio tool a "sonic microscope" for multitrack recordings mixing adjustements etc.
Is be very little hot after 5 hours..and yes with deep low clean bass, neutral mids and highs, active filters with 3 micro switches (4 positions every one )
: treble tilt, bass tilt, bass roll-off + one trimmer 7 positions for input dB sensitivity

final PAC
Hello members,
it is done! PAC is alive. Pre Amp Controller. An input and volume switcher (pssive preamp).
I built it to use it with Waynes Line Stage, ACP+, B1 Korg NUTUBE and a few more. It is like a modular system.....
The pcbs are available as a kit. The Ap..e remote is easy to programme. The programme / sketch for the Ardu..o is available for download.
Good night!
