Now the back of the beast... tapping it with a finger results in some resonance.. hope there is no microphony.

I would bypass the mundorf with such a PIO if I would feel any remaining hardness after burn in. Keep in mind that the mica cap and the Mundorf burn in a bit longer in time than the PIO. In geneal don't change any components before you clock 48 hours of play. The shunt breaks in too. Leave the system on at all times during those initial 48 hours. Only change your load resistor if you have to. What you ended up for load on another phono it may change with this phono.
Wishes for a non problematic first audition.

Its the case, not the element. You can bathe it in hot melt later when burned in and you will be familiar enough. Then you can positively say if the silicone glue damping helped or not. Let us know.

I am starting with 39k ohm cart load...

Forgive my ignorance but do you mean PIO 47nF ?

What does PIO mean ?

Is 15.7 nf a silver mica ?

PIO=Paper In Oil.

Yes I would use the same 47nF CCCP pio cap to bypass the output cap. Is it the standard metalized film Mundorf?

Yes the light brown boxy beast is silver mica.

Yes, it is the basic Mundorf... I m using it in my CDP output stage with good results. I also have some 4.7u Sonicap.. should I try those instead ?

Don't know about Mundorf VS Sonic, you have to make your comparisons at your leisure I guess.

And if all those super cheap capacitors worked for so many people in this thread, avoiding very high costs if with brand name audio caps, I guess that they will work a treat for you too.

Thank Soyuz Sovetskikh Sotsialisticheskikh Respublik for its contribution here.

Hi Salas

Just completed the rig.

No noises, no hum, very good sound even without burning...

Must let it burn for some time to be able to comment.

One thing I must say... the shunt is really silent.

Regards

Ricardo

Now the pictures.... sorry for the bad quality.

Overview.. (Do not mind the case ! It was borrowed from another project called "reviving the Aiwa tape dack")

After two records it is already walking over the Meridian... Bass speed is very good indeed !!!
