Calling all SL-1200/1210 owners!

Interesting!

But could I ask a couple of questions please?

1. Ignoring PSU's for the moment, Is there any difference in circuitry between that board in the link above and the Phono1 and Phono2? (I'd already been looking and they figure in my short list).

2. Would it be possible purchase the board and four PSU's together, and at what price?

3. If I purchased four PSU's I assume it would be preferable to use four separate transformers, bridges etc. Yes?

Cheers,
Mike.

Don't dissapoint me I thought you knew what was what and could use a soldering iron.

This is the basic board, I thought you wanted cheap. Same as built in the integrateds and in the P90 pre. Phono2 more complicated.

In the pic and in the offer there is only one regulator board, but each of the gain stages can be powered seperately so if you wish to power them seperately you would need four regulator boards. PSU are £190 each, your money is gone!

Any techie has got a couple of trannies lying around and a few caps I though you were one, I was trying to help but if you want it built then you pay for it built.

Doh!.... I'm a clown and should pay more attention to what I'm typing!

Please re-read questions 2 & 3 and where it says 'PSU' please insert 'Reg'.



I kind of knew what the answer to Q1 would be, but I thought I'd check anyway. One never knows, maybe you could be persuaded to sell a Phono2 board! (he said, expecting the answer 'No'!)

Come on it is a simple regulator board, a couple of resistors and comping caps one side of the chip a couple the other, when you get one you can copy another three on some veroboard or similar. I want to see you do some techie.

Phono2 - Same board layout different quality on some comps. When you get it look at it and work it out yourself. Stick to the values replace the quality. The laws of diminishing returns apply. You could go whole hog with Shinko res and top dog caps, you could change the op-amps but I have found no better, they are just selected for the phono 2.

Awww dammit!.....

A chalange has been made! And there was me just trying to be lazy...... I'm just off to eBay.

There... Done!

Let's see what can be done with this wee beastie then!

Keep it on-line and keep us amused with progress, even if you fry it

Don't worry though if you cook it I will haul you out the sh1t by doing it properly for you

Pffft....

I'll make it even better than your own and sell it back to you (with a retailers hat on) for three times the price!

That is just what most manufacturers do, what is original

Anyway for that you have another challenge, seeing as you haven't decided on which cartridge yet it will come sans input res and comp and sans gain res, so you can have the pleasure of working it out when you decide which cartridge you are going to use. BUT I am alway here for you young sprog mi lad, as long as there is a little deference to your Jedi master, we can get there together.

And there will be lots of celebration and

Okeydokey....

When I get started I'll start a new thread and documant 'The Build' with photo's 'n stuff.
I think I'll have to source some nice boxes for it all to live in though rather than the scabby bits of tat I've got lying about. It'll have to be a two box affair too, it'd just be rude not to!

Night night.

First lesson - never put a transformer (especially if it is a frame) anywhere near a phono stage, even moving magnet. Two boxes are essential unless you are only using one small 50va (or under) torroid, and then aligned so the field null points to the phono pcb.
