Hi Marco-i have looked at your forum and i don't find it of interest to me !

Nothing personal ! I only regularly view two forums,although i have signed up for several more which i view when i have a specific need.

Start an over 50s dating site and i would be interested ! :lol:

Hi-it seems the DL 103 needs more "weight" at the headshell end to sound it's best. A common "bodge" is a bit of blutak and a 20p piece on the headshell (i kid you not !) and a corresponding increase in the counterweight to bring it back into balance.All to do with its compliance...

Hi-the Cliff connectors as WAD used are suitable for 250V AC so may be ok for your DC voltage and are a lot easier to use than the ones WD now use on the 3 series pre/phonos. I use them on my ECL82 but the HT is not as high as yours. http://www.rapidonline.com/productinfo.aspx?tier1URL=Cables-Connec...

Hi-from what Steve S has said (on the "other" forum i think) it would seem 2 fixed resistors may be the way to go sound wise !

If a pot balances the hum on its central setting then fixed resistors would seem to make good sense.

If i keep PT15 i will try it on that at some time.

6D22s diode bridge ?

Hi-is there any reason why it may not be a good idea to use 4 off 6D22s diodes in a bridge formation ?

Quad 11 improvements.

Hi-i have a pair of Quad 11's which were "improved" quite a few years ago with new resistors and some "bigger" capacitors. They have not seen regular use for a couple of years because other,better performing ,PP and SE amps have come my way. I would be loath to part with them,for...

The figure i saw for black Delrin was 500v/mm.

So for what i am using it for there should be no probs.

Thanks Darren for alerting me about a potential problem.

This seems to suggest "very good insulating properties" !

BTW Philip, Do remember that Acetal is not particularly good at electrical insulation. Esp the black type as it contains carbon. Never use it for isolating any HT on your amp projects. :shock: Hi Darren-that worries me ! I checked the insulating properties of Delrin on the internet and was led to b...

Hi-a lot of "plastics" and "nylons" can be machined quite easily.

I have used Delrin quite a lot on various projects and that machines very nicely on my home lathe.I get mine from e-bay seller" UK Roy "
