Resistor upgrade
« on: July 09, 2017, 01:08:04 am »

   I am using my stereomour 2 for nearly one year.And ı am sure that she is spectacular.l've changed claritycap mr 2.7uf caps to jantzen silver z cap 4.7uf and these caps suit to my liking more.i want to make some resistor upgrade.
   220 r charcroft z-foil (8 ) for stock ones
   0.15 r mills 5w (4) for stock ones
   33k charcroft z-foil (2) for stock resistors between volume pot and
  Balance pot.
        I need to know that is it worth to make these changes
 Any idea will be appreciated.thank you.

Some of these are completely out of the signal path, and some are grid stoppers that are in the signal path.  I haven't heard a difference when swapping these out for different parts.

   0.15 r mills 5w (4) for stock ones

I wouldn't mess with these. The 5W Mills parts might not even fit.
   33k charcroft z-foil (2) for stock resistors between volume pot and
  Balance pot.
The better idea here is to get rid of the volume and balance pot and install the attenuator upgrade.

 Thank you very much for your reply.Right now ı am using stereomour as a power amp with volume pot way up.my pre-amp is mingda mc 7r.so..i will keep the stock parts . Thank you again

If you aren't using the level controls, you can install wire jumpers across each 33K resistor.  This will disable the balance control and isn't ideal if the amp is returned to service as an integrated though.
