We've also given Frank a spiffy new title to go with his gray hair.

Hi,

We've also given Frank a spiffy new title to go with his gray hair.

Aaaaaarghhhhhhh....
Just when I've been spending most of the Summer biking to keep me fit....Pfffttttt.

Thanks to all you guys for putting up with me. It's a pleasure knowing you all.

While I'm at it, congrats to Variac and Netlist for being the newest moderators. You'll do a great job.

A special thanks to you SY and the modcrew for the honours.

Cheers,

[SY]

I've been hiking for the same purposes but the beard keeps getting grayer and the salt is overtaking the pepper.

Many Congrats to you Frank.

I figured you'd be the first one here (Enlightened all over again ). Peter's not far behind though.

In the mean time, a toast to you.

this is Frank's first post, in case there was any confusion between quantity and quality ...

MC Stepup using 6dj8 Post #9
Sorry I spotted your problem this late.
I use a circuit that may just do the trick.
Basically I don't like to use transformers at this very critical frontend since any flaws will be amplified througout the audio chain.
Here is what you can do :

- 2 x 6dj8 in parallel per channel (dual mono) at 24 vdc regulated with a 7824 ic.
- regulate the 12 vdc heater supply with a 7812 ( 2 x 6 vdc)

- use a fet such as BF 244A as a current source for the anode current regulation ( or similar fet, idss must be the same ).

-cathodes are grounded.

-signal is taken from the anodes.

I used MIT metalized polysterenes since I could not find any colourations.(Metalized teflon is best on paper here but was not commercially available at the time)
Keep in mind to keep the signal path as short as feasable.

This sounds very well,noise is no problem unless perhaps if you'd
use ridiculously low output MC's.
Low level information is excellent provided the rest of the system is up to it.Transients are lightning fast,I use OTL amps so nothing there in the way of ringing or overshoot.
Frequency response is deliberately limited from 16 Hz to 1MHz in order not to burn the woofer coils.

The cartridge is not loaded and no input cap is used for ultimate transparancy.I used a Jan Allaerts MC hand built cartridge but others may require loading.Anyway that's simple enough to solve.

Best rgds,

Frank De Grove.
