Simplistic NJFET RIAA

[merlin el mago]

V grade jfets are generally used in amp front end, or by John Curl.... (hat off!)

Is not the only.....

Thks for the info Salas.

Can anybody who got V from that sale, measure say 10 random pcs and tell me the average?[/QUOTE

I got 100, but haven' t mesured them yet. Tomorow I will mesure some for you.

If you have in mind to sell some with good prices I'll be interested in some with 10.5mA Idss. Let me know?

 

[vgeorge]

Let me mesure them first. I have one 10.5 idss Bl. How many do you want?

 

[MiiB]

Can anyone guide to the final schematic..

Thanks

Of course, but he's the Master! As least for high current preamp use.
Again, hat off!

For what? Merlin's Low MC for 10.5mA Idss?

Of course. And when Merlin starts designing and becomes famous then we will have the first with 3 letter acronym or more.

Yes please Merlin's Low MC for 10.5mA Idss

Thread is a bit long to plough thru

Thanx

 

[AndrewT]

I put forward JLH for a three letter acronym.

 

[Salas]

Correct! A great man.

Switching C10 with on board dip makes it normal MC.

I am very, very infuriated, I have paid to Parts Connexion extra money for matched pairs & I have received:

Channel Left:
R3 47K
R4 6K8
R5 1Meg13

Channel Right
R3 46K8
R4 6K9
R5 998K

Thks in advance Ricardo let me know how can do with these mix.

Are these the real values on your build ? I wish you had made pairs before soldering.
I also need to know the real 3k3 value.

Admiting 3k3 = 3k3 sharp, in the Left channel you can // 1M5 to 47k and 300p // 47n......you will be very close to heaven.

Now the other channel is bad.... the main problem is 6k9 that should go down to 6k77 .... You will gain lots of presence that way in this channel. Also I would go for 1M7 // 46k8 and 300p // 47n.

All this with 15.6n // 330p as initially.

Now it would really be good to have both channels with the same values... do you have more resistors so you can make equivalent pairs ?

Regards
Ricardo

How many do you have? what price?

 

[RCruz]

Come on Merlin.... I need your feedback !

My new riaa might be exactly like yours so I must learn a lot now.
