Hallo Silver! I'm very sorry to read about all this nightmere of yours...I still have my old Lowrey T2 somewhere in the basement...Its a sad story back in 1983 when I had to lent it to my late(now) brother Luke for some gigs. The organ had two manuals, a one oct pedalboard, an external combo amplifier with a 12'speaker and a big horn, and a volume pedal all connected to the organ with big fat cables ending in multi-pins. Sadly thieves broke into the rehearsing studio and stole many things icluding my amp(the power on swicth was in it) and my pedal board...I tried for years to fix my organ to play installing new power swicth ect and got nothing at all.So it ended in the basement.
I give you some alternate route.
1.Go to Emporio600 site(JazzHooves) and then to Peterborough Organs in UK, maybe you can find some good stuff there.
2.Go to Classic Organ Works site. They do a fantastic work. They will give you advice(sign up)
3.Go for a virtual organ solution. I believe its the best way nowadays.. (maybe the only one).It's not difficult, and not so expencive if make a good planning of what exactly you want.Buy two 49keys Cme keyboards(fantastic features, usb fast plug and play, a bit soft-for my taste-touch, can use the drum pads for stop on/off) about 130euros each, then download Hauptwerk free edition and Midiger 216(free) theater organ.The expencive thing is the pedalboard(midi).Bohm, Classic organ works they make all sort off, starting at 1000euros...Install Asio 4all(free) for zero latency when playing from your computer.
Go to PCorgan.com.The guy gives huge information there, hard work.
I hope I did a little help for your problem.Post me here if you feel like...
greetings
Panos
