Simplistic NJFET RIAA

[RCruz]

So is the EL value strict ?

I can use 470u, thet I have in stock, or not ?

Salas I have four real Toshibas K389V could I do a new simplistic for my Denon DL103R

Idss
1- 12.26mA
2- 13.70mA
3- 14.13mA
4- 14.96mA

You can use them instead of the 100uF in the experimental but double up where you see 1000uF.

Will reply in due time bcs I will have to tweak the sim model.

Hello Guys, I have been reading around this thread but it's hard to find info in the 800+ pages so I guess you won't mind me asking a few questions:

From what I can understand the simplistic can be configured for MM carts right?
Is the schematic in the first post the latest one?
Is there any PCB available that includes the regulators, like the mesmerize buffer?
If no pcb available, is there a tested layout around?

A more practical question, what is a ballpark figure for parts cost of the phono stage and recomended regulators?

This should be a starting point!

No PCB available each simplistic is tailored by Salas depending your cartridge and the Idss of your SK170BL stash.

Cost depends components used.

See Wiki page if there is one can meet your cart specs link:

The starting point is the pdf build instruction in the first post

Better have a look at the PDF at the first page to begin with.

Hi Ricardo

This is the 'turret board'.
Also sometimes called a 'group panel'.

Most people use this for high-voltage stuff.
Often find it in 50s' 60s' guitar amps, before PCBs.

The board in the pics is 60mm x 300mm & has 2 rows of 30 turrets.
The spare holes are on a 10mm pitch & you can get spare turrets, which you just rivet into position using a centre-punch & hammer.

Not much good for Op-Amps !
But I think it's great for discrete stuff like regs. or the simplistic.

It also comes in larger perforated sheets, so any size is possible; just rivet in your own turrets.
Glass-fibre or Tufnol.

What I like about it is :-
You can solder components across the turrets, without cutting the leads short; good for experimental values.
Can wire interconnects below-board for neatness or above for visibility & ease of access; you can work on turret boards fixed in a case without removing them to get to the back.
Also good for mounting chunky bits like ex-Soviet military capacitors.
Wires can also be laced through spare holes, to relieve tension on solder joints.

Blurb...
...blurb...
Blurb...!

You can tell I like the stuff, yes ?

One row is often used as the ground row & the top the live row.
Just rivet in extra turrets in between, where you need them.
The whole thing can be laid out just like the schematic in fact, with all wiring on the surface which is easy to see & solder.

Try it out it's Grrreeeaaatttt !!!

Cheers

Si.

PS...only about 0.000000001 pF capacitance ( we hope ! )
