Suitable relay for delay cicuit

[Dino-Indo]

Hi Nuuk,

Many thanks for sharing the buffer delay circuit for gainclone in your website!

I'm enjoying my point to point LM3876 equipped with Nelson Pass B1 Buffer Preamp with the delay circuit in place

Previously there was thump during on and off and now it's gone!!

The sweet sounding of LM3876 coupled with Nelson Pass B1 Buffer Preamp achieved!!

Again, thanks!!

Best regards from Jakarta - Indonesia

Glad you are enjoying it Dino. I'm about to re-arrange my system and will be using a delay circuit again on the buffers so I can turn it all on with one switch. I add my thanks to whoever designed that circuit originally!

Hello,

I know that this thread is very old. All the images in it are now defunct, so I cannot use them to help me devise a solution for my circuit.

I am trying to use your approach on a tube front end super-triode, feeding a unity gain OPA541. (Super Triode Connected (STC) chip amp)

I got here from Building a Gainclone chip amp with various active buffers using opamps and discrete components. .

There are no R-C components on the input of the OPA541. I'm trying to figure out if I can use the delay to switch out the shorted inputs on the chip without any problems.

I am a paint-by -number type of builder. I don't have enough time to spend studying more electronics. I build for fun so please be a little patient.

I have attached some images.

Thank you for your help.
