Vintage Synth Repair

I haven’t measured its temperature as I do not have this meter.


As soon as I switch off and touch it for 2 seconds I do not burn my finger
but wasn’t able to keep it on it either as it was too hot.


I have now fitted the replacement with a small heat-sink but just the same it works too hot.
Thanks for you help...

How hot is it? 70C? 80C? Warm to hot is normal, burn fingers in 2 seconds is not.

Anyone has or has met
with an Alesis ion
(Q01)?
I noted Q2=TOP223Y in the
primary of SMPS runs
extremely hot (caution: switch off!!)
Is this normal? It has no
heat-sink!
