content: ===UPDATE===Thanks to Aargee selling his trashy looking Fluke PM3355 for $50.I should now be able to repair my my angelic $70 Phillips PM3065.If VTL still needs a potentiometerHe gets one gratis.(images removed)Philips/Fluke models PM3050 PM3055 PM3065 PM3070 have some interchangeable partsLooking for replacement potentiometers or (worst case) two replacement front panel boards for a Philips PM3065 scope.The potentiometers are shown on the right side of the below photo. The one I'm repairing (for personal use) has multiple broken shafts.Description/ordering code of pots from service manual:PP17 20% 10K 5322 101 30546I will update this post if I get replacements otherwise I still need em.Any additional ideas or mod suggestions welcome.

content: Thanks guysSourcing through a parts company and shipping a whole scope from Europe and the US is beyond economical repair at this stage.The assholes that broke it cost me an extra $100 already so this scopes running into the negative dollars value range.But like a fool who has already invested so much time in getting it running I want to fix it.I'm at the point where I need a handful of potentiometers and probably safer to get the complete boards from a non functioning unit.This will also make it cost effective to send worldwide.Not ideal, but if anyone has repaired them and knows some substitutes that can be fitted without destroying the PCB. I'm open to that as well.

content: Where are you in Aus, I'm is SE Qld?I have a PM3355 DSO that has seen some trauma to the case but the panel is intact and looks like the same configuration. Pretty sure it all still works.It was to be a do-up project but time and motion, etc... I can check it when I get home if you're interested.- Rob.
