Vintage Synth Repair

Right where do I start,

My little AXXE (mk2 black and orange) seems to having a strange envelope
problem. When you turn the arp on, and its set to S and H with the keyboard
trigger repeat set, the envelope section works as normal following the LFO
speed. After about 15 seconds or so it starts to drop out in a very slow osc
type of way (very vague I know). The volume drops and everything starts to go
out of tune etc then returns to normal and then back again.
At this point there normally is a tone which is on tone lower than the lowest
key.
When you play notes straight on the keyboard it does the exact same thing and
it appears to be some sort of component break down somewhere on the trigger
section. The keyboard intermittently stops working too and the CV gate sockets
won't work.
Its been to my repair man who needs schems, nothing is obviously knackered but
he's at a lose without more data.

Thanks for reading this rubbish and all the best to you list guys.

I forwarded your note over to the ARP Odyssey list.  Maybe someone over there can help.  If so, they'll be in contact with you.  If you need an ARP factory trained technician, there are a few listed on the Technicians page of the Odyssey web site.

Maybe a power supply problem?? sagging? pitch response out, and volume
problems at the same time suggests maybe something is up there to me. This
is quite obvious though... did he check the power rails when the weirdness
was hapenning?

my flatmate fixed a totally dead arp axxe a few weeks ago, he managed to
work out what was what in the axxe by using odyssey schematics from the net.
though you may not want to pay a tech to work that way, its a bit slow....
