If you are going to the expense of repairing, I would recommend that you have a look at the works done in the following post. Aaron ATS-4 can be upgraded reasonably easily and there are number of posts on this forum regarding this. Good luck with the repairs.

Good luck with it.

PM sent.

Thanks for that. I have a set of ATS-4 which I will be upgrading at some stage and really glad to hear the before and after with these upgrades.

I highly recommend @Tubularbells

Item: Platter for a Lenco B55 turntable Price Range: Negotiable Item Condition: New or Used Extra Info: Have an issue with a deck I am restoring and was wondering if there light platter for a Lenco including C clip out there.

Welcome to the group and good luck with search.

Highly recommend Doug for all any work, so far he has done work for me on some speakers, amp, pre-amp and cd player has been all good work. Have found him to be open, honest, reliable and very fair on pricing.

Anthony, I have a real soft spot for the Optonica gear as well and have the following: RP-2727 Turntable SM-4100 Amplifier RT-5200 Cassette Deck and ST-5100 Tuner. My old Marantz gear has a bit more history for me so I am currently using them for my Study system with headphones mostly, but at some stage I will get Tubularbells to give my Optonica gear a service and then they will get a lot more use. I was running the SM4100 with Onkyo U3500 speakers on the weekend, 20-40 W 8 ohm 100 db/W (50cm) and they sounded lovely the SM4100 is only 2

Buzz, Good luck with that. I have an Optonica SM-4100 that I played around with on the weekend and it sounds great. Don't know if it might help but Peter Vis put up a very detailed website on his work on a SM-4100 at the website below. Not sure if this will assist but the 4100 is not very different to the 5100 so might be worth a look for fault finding purposes. https://www.petervis.com/Amplifiers/optonica-sm-4100/optonica-sm-4100.html

Bills cables are excellent. Use them and love them

I think that there is a big difference between "Vintage" and just plain "Old". Vintage in my opinion, gives an impression of quality whilst Old may be quality or not. I see vintage used in ads all over the place for disposable junk that was engineered with planned obsolescence built-in twenty plus years ago that people are trying to flog off today as "vintage". I think that vintage in audio should be at least 30 years with a caveat on quality.

Sounds like a good starting point for both a 2 channel and headfi listening. Not sure about the Sennheiser cans but Head-fi.org is a great forum for headphone reviews who can tell you alot more about what is on offer. In regards to your amp, headphones and speakers, this post is probably better suited in https://www.stereo.net.au/forums/forum/117-beginners-purchasing-advice/ Otherwise, have fun and good luck.
