Hi everyone, new poster from Melbourne Australia here.
I have an old Mark Levinson 336 which has been in the family for a while now (over 15 years) getting recapped by a competent tech here in Australia. It had prior history being recapped once when I was still living in Singapore. During the recent re-cap there was some damage discovered on the left channel which the tech cleaned up and replaced the damaged cap & resistors (1st picture)
However on first power up 15 seconds in there was a pop and some white smoke which is obviously a bad sign. Luckily the damage isn’t severe, one of the circuit traces lifted (last picture). This is beyond just simple re-capping now and my tech is after the service manual & schematics to try and help me out. I’ve approached the local Mark Levinson importer but they are saying they do not support it as it is too old, and they do not have the service manual or schematics, only a service bulletin.
I’ve seen a few 336 repairs here so we thought we would reach out and ask if anyone has a copy of the service manual or schematics they are willing to share.
Thank you very much in advance.

@levinson mark thank you so much! I’ll report back if we manage to find success in fixing the issue.
All yellow capacitors need to be replaced. They explode in many ml models. This is a known problem. Change everything to np0.
