Simplistic NJFET RIAA

36VCT. Its just another way to state 18-0-18V I guess.

I thought it was 36-0-36. If it was dual winding, you could have a separate one for each channel.

 

[Salas]

Its 18-0-18V not 18+18V but no problem since he just needs the across value 36V here. Maybe he got two of those Tx.

Yes, was just what was available in the right combination of voltage, VA, and $$.

 

[Salas]

You got a pair, yes?

And????
Me, I just can not stop listening to music..... Salas phono is addictive.

 

[skouliki]

Salas your phono sounds bloody good!!!
Granted i've only listened one album so far, it trashes my modded VLPS in terms of resolution, soundstage and naturalness. Congratulations for you design!

Vgeorge you're going for a mellow night music-wise eh?
Im gonna rock!!
Next for a spin :

Thanks to you and all the other guys for the support

Nothing much, enjoy. Do you manage to listen with low hum & buzz when still in the open?

 

[skouliki]

I have to turn the volume almost all the way to max to hear buzz and a whining sound, which i guess will dissapear when i box the boards!

 

[Salas]

Seems rather normal at this state. Whining should be further harmonic noise because oscillation in open loop is more difficult. Is it like mid-bass whining? Like boiling, or like a whistle?

 

[skouliki]

More like a whistle and located on one channel, it is really faint though. Just rechecked and i turned volume to max and standed about half a meter from speaker to listen

 

[Salas]

Most probably benign. Play records to work and loosen the electrolytics.

It sounds awesome!

But to be fair for comparisons sake i havent listened to other versions

 

[Salas]

Do you use coaxial signal cable at least? Is bass firm enough although in early run stage?

If you mean the interconnect cable coming from the TT is a coaxial. The cables from the rca to board is PTFE silver plated cable which i didnt even twist very well
