Stereomour II / Re: Another failed voltage check
« Last post by SamJ on July 11, 2025, 05:10:14 AM »
PB,

I'll check that and get some photos up as well.  I don't THINK i had the 2A3s installed incorrectly, but there's alway a chance there. 

Thanks for the quick response!

Do any of the 130 ohm 2W resistors measure open when you check them with your meter (with the amp off)?  If so, you likely plugged in a 2A3 without paying attention to the fat vs. skinny pins, which will destroy one of those resistors and leave you with dead voltages on one side (or both if you are unlucky and force both 2A3 tubes into the sockets the wrong way). 

As always, it's also a good idea to post build photos along with stuff like this.

Wanted to say the new shirts look great and I just ordered one.  8) New site looks great as well. 

I love my mainline and eros2 setup, and would love for there to be more upgrade kits to soup up these and other kits in a polished official bottlehead manner.  I did make some mods to a speedballed crack, but I'm hesitant to mess around with the more expensive kits outside an an official kit. 

Just wanted to provide some new product food for thought!  You likely have a sizable captive audience of people that have maxed out on your current kits (I'm limited to headphone use).

Hi Mike, I know you reached out after you posted this so just closing the loop: we don’t provide the manual prior to purchase.

The upgrade itself involves populating and soldering parts on a printed circuit board, then moving some of the wiring around to connect it. It also replaces the original potentiometers with higher quality ones which are installed on a separate circuit board.

If you have other questions you can definitely let us know.

Is there any way to see what's involved in installing the upgrade before buying it?

Stereomour II / Another failed voltage check
« Last post by SamJ on July 10, 2025, 11:22:06 AM »
Same as figby, after a good resistance check and lots of comparing picture to result, I have some wayward DC voltages. Of note the two LEDs for the right channel aren't lighting up.  I reflowed all the connections, including at the terminal strips.  All tubes glow normally and I haven't had any pops or buzzing, smoke, etc.  I'm sure I screwed something obvious up. 

here are my wayward voltages:

14. 1.856 (170-230)
15. 0.302 (58)
17.  1.007 (0)
19.  2.996 (395)
20.  2.848 (365)
34.  3.014 (392)
36.  .305 (58)
37.  .302 (58)
39.  .302 (58)
40. .299  (58)

Happy update: Matt Jabloner / MattyBlue Speaker Machine Shop has agreed to send me two special-order "Subettes."
Thank you for the referral and look forward to whatever new speaker products you might introduce!

Definitely. Our focus is on our two new amps and getting inventory back to a steady state, so nothing in the works as of now. We’ll post here (and everywhere we can think of) when we have more to share.
