401 rebuild

Post by Ant » Sat Oct 12, 2019 2:11 pm

Just finished this one for savvypaul, or 99.999% finished, bloody feet still haven't turned up...

In that shot it temporarily has a borrowed SPU on it to check that the alignment was spot on, which it is. It will have an SPU on it when it goes home. As the SPU is not mine, it was then taken straight back off and stored away snug in its box.
It has some temporary feet on it to make it useable until the proper ones finally turn up. or don't, in which case i will be mildly annoyed an have to make some

Its a big bugger at about 23 1/2" wide, that monstrous ortofon ta210 arm is longer than most 12" arms in terms of spindle to pivot distance. They usually range somewhere around 290-295mm, that ortofon is 316.5 so is about an inch further out than the norm.

spinning 12" singles is fun, the Missus is collecting them at the moment, mostly 80s stuff. They don't half sound good though so I'm not complaining... Much....

I put the dynavector ultimo 20a in it once the SPU was put away. The arm needs alot of headshell weight to balance up, the headshell that comes with it is a 15g one, so all up with that cart in it its about 25g on the end of the arm. It does mean that medium to high compliance carts wont like it, I put the SL15 E LL (one of our wills favourites) in the headshell and got an immediate resonance out of it because the SL is high compliance at 24. the SPU is 8. A different bit of rubber was used in the assembly to make it useable with SME arms in 1968 when it was made. The Dynavector compliance is also listed as 8, its probably abit more but not a huge amount, id estimate about 12 ish so it works fine

Its on some different feet right now to raise it up higher as the arm cable that comes with the ortofon is a stupid gargantuan cable that looks like it could string a suspension bridge. its not very bendy, about a half inch thick, and is cumbersome and awkward to use. Don't even think about using on a suspended subchassis deck, it would be utterly impossible to get it to work. In the earlier shots Id used a different cable. But other than the stupid cable the arm is rather nice.
The feet were actually made by Richard Higgins, they came with one of the very first lencos I had. That one became the first teardrop shaped 75 I did and is still going strong at mi dad's. It's been arou d the block that one...

It will be here for a little while until it gets collected, so ill get to enjoy it for a short time
on to the next one :mrgreen:
