Jason's Techy T/T blog and the arrival of the Jelco 'big boy' c/w

[Marco]

Hi Jason,

I am puzzled about how to get the VTA correct and use a 103 w/o spacer on a headshell like the LH-18.

The only way is to use a thicker mat, which does the same job as the spacer without imposing a negative effect on the cartridge... Therefore the answer is to remove the spacer and add the thicker Herbie's-style mat, available from Dave

I would also add that Dave's 'cartridge stabiliser' solution above is very effective with lighter headshells than the LH-18. A fairly thick brass 'plate' such as this will be subject to little, if any, resonance, and in fact would add some much needed rigidity and damping to lightweight headshells.

It is 8gm and soft copper. It gives the 103 something to "work against". A soft spacer won't couple well.

Agreed

Thanks guys,
I'll have to look into the mats (and big boy counterweight). I don't want to give up on my AT LH-18.

My 103 is sounding simply amazing right now. I'm loving it.


Dave,
One other thing - don't know if Marco told you, but I bought his old KAB PSU. He told me that you can assist me in how to convert it from 220 to 120V. I'll buy you a virtual beer.

Hi Jason

I can get you going no problem! When you get it open up the box. It should be obvious what to do, but if not just send me a photo and I'll give you step by step instructions.

I've also just received a 21V power supply from Paul Hynes, and I'm going to compare that with my current Diy supply using a 317 regulator.

Have you tried out the Paul Hynes 21v supply yet? I had one coming from Paul for the SL-1210 to pitch against the Time Step PSU, but he is now making it up to power my Kenwood DD instead. As a dramatically more advanced supply than any LM317 variant could ever be, the Paul Hynes PSU should be a clear improvement - I await your thoughts with interest!

What the state of play now with your Techy, Shugs? There have been no updates on your blog

Yes the Paul Hynes psu is connected up but I haven't yet had time to evaluate it compared to my 317 supply. I need to get used to the other changes that I've recently made in my vinyl system before making the comparison.

How's the LH-18 doing, John - still hitting the spot?

It's sitting in the spare room, while the Kenwood sings! I am going to take it do Dave for the motor dynamics mod when I have a bit of time, and maybe that will bring it up to where I'd like it to be! We shall see (or rather hear).

While I am close to making up my mind on the Technics, a further £60 to give it a chance is sensible. If it doesn't work out, then someone will get the chance to get a virtually new deck, with Time Step PSU, AO modified Technics arm, OL Rega armboard, and a pair of Sumiko headshells!
