HI, Iwas just going to explain but you beat me to it !

My local model shop sells 3 different thicknesses of brass but only 1 of copper - 1.5mm! Cutting is the problem. Cost is another factor - the copper sheet is 5 times the price and the waste factor is high!

I don't know! Most commercial screens are brass or tin. What are the HDAM screens made of?

I will be using the thicker brass for a screen to the front panel as I may hang some PSU bits on it.

Hehe! Good reasoning. I hope it makes an improvement. Is your clock crystal also screened or grounded? Does it even matter?? Will check mine next time I go down on her..

The HDAMs are copper coated, umm, steel? Actually I don't know.

Now I have a few things I really must do to mine - some psu work (extra regs), check crystal for grounding, and add proper phono sockets.

Hi.

Yep screening the clock is also on the list - when I can decide which one - I have tricord2, LC and audiocom plus I have just received a mini board with a colpitts ? oscillator which I may use as the basis for a Kwak clock!

Ah, cool, loadsa clocks! I use an Audiocom 'DVC-1 master clock', which works a treat (fed 5v from a large external diy psu). This was their budget (£100) alternative to the Superclock (and 2, 3 etc.!). However, as Brent tells us, they now sell at hugely reduced prices through Ebay, so they're no longer a total wallet-busting skank.

Hey! Ebay?

Here come the quotes for the custom toroids:

I used Ray's latest suggestion (found here), but had to decide
on some manufacturing details as well to get the quote.

So I went for:
- a potted centre with M5-thread
- a static screen (made of copper foil)
- only one primary winding of 230V

This is up for discussion, of course....


The net prices I was quoted are:

€ 23,90 - 24,50 ea. for 10 pieces
€ 26,00 - 27,05 ea. for 20 pieces

The two manufacturers are very close with their pricing...

Including german VAT, shipping the bulk to my place and distributing
the toroids within Europe, the final price for you should be around
€ 39,00 for ground mail and max. € 43,00 for air mail.

[Michi124]

It's the other way around, sorry...

€ 23,90 - 24,50 ea. for 20 pieces
€ 26,00 - 27,05 ea. for 10 pieces

What do you think?
Is the quote from Amplimo in already?

[Fidelity Audio]

whooo these are very good prices

25 euro is about £18- £20 i think

Are they oxygen free copper?

I may have to buy a few lol

[SimontY]

39.00 EUR = 26.7060 GBP (xe.com)

I think it's a very good price considering the low quantity and custom nature of it.

To those of a more techincal persuasion than myself I pose the question - will this transformer be superior to the existing toroid in the KI version?

Is this an upgrade or a spare part? (no doubt it's definately an upgrade for those using a traditional 'I' core tx i.e. CD63 and CD63SE and CD67OSE.

.............will this transformer be superior to the existing toroid in the KI version? ..........

Hi.

As you say .. for those with a standard Tx, it will be an upgrade, without doubt!!!

For KI users, it depends on which way you look at it. In my opinion, YES. ( even if it is not OFC )

1. It is higher VA rating. Therefore better regulation.
2. It has more 5v windings to provide independant supplies to Analog and digital sections of the cd-p.

PS at that price, it's worth a try .. same price as a set of '627s !!
