Quick info:
I can confirm that wiring switches directly across the outer pot pins works well for both mono and mute functions.

Hi Joe,
highly interested in the V76!

Best regards,

Udo.

Wow,
that's a lot of info,thank you very much indeed!
I quickly digged a bit through your new small pieces of gear.....now that triggers a lot of thoughts and ideas in me
E.g.: Where can I ask things about the STATTEN,will there be a thread too?

Best regards,

Udo.

Hi Joe, so I´m the one starting questions (again),hahaha :) Have built the new AMPHEAD II in about half an hour,easy one.Very well done again Joe! 1.:For the 2 x 10r (RF+ & RF-): I will run the amp head from +/-24vdc,Zeners omitted,I use OPA2604s.Must the value be changed? Your instructions cover th...

Hi Joe,

quick question:My kits came with 6 x 100uf/50 lytics each,but they look like they are polarized (have minus-markings).
They have writings saying "NPR".Does that just mean "Non-Polarized Radial"?
If yes then I'm save to proceed.....

Best regards,

Udo.

Some more…... Fantastic Udo thanks :-) I would like to use some of these photos up on our facebook page if that is ok with you? https://www.facebook.com/jlmaudio1 Absolutely Joe,thank you.Sorry for not having better pics,I'm no photographer and only have an old and cheap camera. Best regards, Udo.

Some more…...

HI Udo Great to hear they went together well and worked perfectly after going around the world twice :-) Looking forward to the 10 x LA500 photo :-) All the best. Hi Joe, excuse me,but I totally forgot to show pictures! Although it´s an old thread meanwhile it might be that one or the other gets in...

It works! Made some real world measurements,first with the resistance decade to get an idea of a useful value range. If anyone is interested: For +/-15dB boost or cut it is around 300 ohms.I'll use a trim pot in that position,maybe 500 ohms or 1k. Next was pot travel.While for a standard fader/pot t...

Set gain trim pot for +15 or +20dB gain Add a resistor or trim pot in series with the pot wire going to 0v to limit the -dB amount to -15 or -20dB. Wow,that was fast,thank you very much Joe! Will try with a resistance decade to get some values later and report back. In case of a series trim pot it ...

Place a SPDT switch between the volume pot wiper wire that discounts the wire from the wiper and switches it to 0v. Thank you Joe, that's what I thought first.In the real setup it turned out that the end position did not really damp the signal down to "somehow" minus infinity.Then I found that the ...

Hi Joe,

hope you're fine.
A quick question:I use the dingo pup as active fader modules,all working pretty good.
I wonder what would be an appropiate way to have a mute on output?
Following circuit is an interface (line level balanced,input Z is 12kOhms).

Any idea?

Thank you in advance,

Udo.

HI Udo Sorry had missed this. It is to hard to explain the constantly moving attack and release times. And the slow attack also varies with ratio and opto moving times. Other than to say they work better than any normal preset attack and release ever :-) Thank you Joe,that's what I expected.I was a...

Hello Joe,

don't know if this has been covered,but do you by accident have some numbers for attack and release times in both "normal" and slow attack modes for us?

Thank you in advance,

best regards,

Udo.

Two more done,worked from start,no issues at all.
These are the last two LA500 kits on earth,hahaha,my #s 9 &10.
Will soon show a pic of them together with my #1 to #8.

Have fun,

Udo.
