I had to counterbalance my Rek o Kut too, when hung a 1-C on it...

Thanks Fela, good to know!

Wow, what a difference a decent amplifier makes! Now getting somewhere with a decent sounding louder cut -some issues with static but I'm still having to counterbalance manually with quite a lot of weight. Does the setup look right?

OK so it's 210 LPI which accounts for the closeness I guess.

( ignore the brackets this is how I have been adding more weight).

Many thanks for this, yes, I'd read your other thread already - super interesting. The 1C I'd been running with a stepup transformer as it's a 500ohm but up until this point It's been a using boat anchor of a power amp so that doesn't help. Some new valves for the R8 arrived today (they were also sm...

Thanks so much for this Soulbear! I did do a search but overwhelmed with posts with those terms - much search harder. Yep, I do have a microscope but no reticule or stand with it (it's supposed to mount to my other overhead but that's a way off) and I find it tough to look through the eyepiece so li...

Mrd, thanks. The Presto 1C is heavier than the Audax, but not that much as to radically change how the machine should work. The type of stylus and blank may make more of a difference, as will the condition/adjustment/lubrication of the pivot points of the suspension. What blanks/stylus are you usin...

Cool project. Comment on this vid, suggests that it's an inside out groove to add some further slight complication: qj3zaLomyxA There are lots of people who can cut small records - there was a guy on here recently cutting 1 inch records, might be worth sounding them out about what you want to do. Re...

Nice! This is great

Great stuff, look forward to following this - what's the boost button for on the top one?!

Really nice!

Not mine, but maybe of use to someone:

Hi, I hadn't thought of selling it. Feel free to drop me a PM and make an offer

No worries. When I was on the original search I considered swapping out the connector for an IEC C8 (figure 8 socket) or similar... I didn't get as far as looking at how straight-forward this is by measuring opening and screw mounting points etc. Good luck!

As above, they seem hard to find.Assuming you have the two pin square thing. I looked back to the ebay link I had and it's dead. I ended up using a CB radio one... I *think* it's this one - https://www.nevadaradio.co.uk/product/nevada-pow-b193a/ not used this company so can't vouch for them. You'll ...

I think there are two different types. If it's the same as mine, I believe its an IEC C11 or it looks a lot like one but with round pins. They don't make them anymore it's a polarised rectangular connection (has a cutout in it). Quite hard to track down a suitable replacement. I found mine listed as...

This is amazing and really helpful.

Can I ask if the Audax head is weirdly light? I'm finding I'm having to add a load of weight to the counterbalance for a 1C am I missing something or doing something stupid?

Hi, after some classic courier handling my Rek-o-kut imperial II arrived with a few issues. The motor had dropped on its mounts and the capstan sheered off so now looks like this - https://i.ibb.co/x7m6SWB/IMG-4281.jpg https://i.ibb.co/zsLfwgj/IMG-4280.jpg Tried to glue the pieces back together and ...

Just picked up one of these - So far I know it's from 1932 it's described as part of a sound film recording machine here: https://www.radiomuseum.org/r/neumann_r21r_2.html and it has studio 2 written on the box. Has anyone got any other info on this? I note that there's a telefunken branded R12a as ...

Yep, it's a weird belt alright. I couldn't find a replacement - the trick in the end for me was to use a rubber o ring from some plumbing connection (I'll check the diameter but likely to be either 32 or 40mm approz) https://www.instagram.com/p/BjHeK56BRoR/
