I don't know how to send a PM to you.

New members can not initiate pm's but you can receive and reply to any you receive from other members.

PM send

Hi meldano, can you PM me please? Thank you.

Daniel, is this for connecting a Bourns encoder going to work with your v2? Thx

I can confirm the circuit of Tombo does work in combination with a Bourns em14 encoder.

Very nice.
If you will use massive aluminum volume knob, apply a smidge of Teflon grease at shaft, where it enters encoder, speeding it with rotation and exercising pushbutton action. With a very heavy knob, it could squeak a little after some time.

I apologize for being terribly lazy, but does someone have an updated/recent BOM (Mouser/RS Components)? Am having difficulty finding all the parts as some are no longer in stock. Thanks 🙏

Here we go, Mouser BOM for 1x uC and 2x Vol boards, i.e. the balanced/differential v2 version 👍

 

[freebee]

Thanks 🙏

It would be better to DIY newbie like me If there are labels of components on PCB silkscreen in BOM.

Alternatives of BOM (Mouser)

Are these OK?

Mouser #: 667-ERA-6AEB202V <- 667-ERA-6ARB202V
Mouser #: 667-EEU-FR1V221 <- 667-EEU-FR1V221BJ
Mouser #: 625-DF02S-E3 <- 625-EDF1DS-E3/77
Mouser #: 583-SR160-B <- 637-SB160
Mouser #: 595-TPIC2810DG4 <- 595-TPIC2810D
Mouser #: 667-EEU-FR1V221 <- 667-EEU-FR1V221B
Mouser #: 647-UKL1A470KDDANATD <- 647-UFG1A470MDM

BTW, I cannot find an alternative of omron Relay ( Mouser #: 653-G6K-2P-DC4.5 )

Have you been able to find the Omron relays?

 

[namghiwook]

Have you been able to find the Omron relays?

I couldn';t find omron relay in Mouser or Digikey, but have bought omron G6K-2P DC5 relay on a local device shopping website.

 

[freebee]

Do you happen to have a website link of the shop?

Do you happen to have a website link of the shop?

I'm in South Korea.

Hey Daniel, got a question regarding the v2 uC and Volume boards:

• For the uC board the pdf manual says C7 47uF/10V, however there is no C7 marked on the board, only up to C6?
  Actually there is a 2nd C6, it is SMD cap right to the ST processor.
  
• For the Volume boards for C1, C2 the pdf manual says 180μF/25V but the Reichelt order number for this position is "RAD FR 220/35", which is 220uF/35V cap. So, is it 180 or 220uF better used?

Thanks!

 

[meldano]

Hi,

• C7 is to the left of X2
• C1/2 feel free to use 180uF or 220uF

 

[starcat]

Compared to a traditional analog pot, what would be the resistance that the amp would see by using this pot? Forgive me if I have missed this somewhere... thanks!

 

[meldano]

20k

 

[Bensen]

Source will see about 20k, the load will see between 2 and 6k.

Or am I missing something?

[Groundloops]

When paralleling multiple boards as multichannel volume control, is it possible to preset attenuation individually per channel or per channel pair to equalize different amplifier gains/driver sensivities?
