Default mods poppulse t150

Hi,

My first experience with mods on my first poppulse (t77) was very good.
I would try again with this t150 mk2:

- Replacing coupling caps with mkp
- Repacing Pot for SMT resistor step attenuator

But I don't know where are coupling caps on this new t150...

There are 3 caps near the audio output. 2 Elna cerafine 47uf between relay and coil, and 1 more (100uf) on the left side of the ta2022.

I think this 2 red caps 47uf are the coupling caps.
If someone can help me...

Can I replace these 47uf with 3,3uf mkp? I don't know the input resistance and I don't want to cut my bass...

What do you think about SMT pot? Actually the pot is ALPS blue one (2x 10kohm). Is it really better to replace this with a SMT attenuator 20kohm?

Many thanks...

Hi there,

I own a POPPULSE T150 MKII and was wondering how the upgrade worked out. I am interested in making my POPPULSE T150 sound better and looking for some guidance.
:-)

Hi Grotius,

Bypassing the volume pot is easy and has made a subtile improvement on my T150 mkII.
