Moreplay Upgrade / Slight channel imbalance after installing the upgrade [resolved]

« Last post by heavycowboy on June 27, 2025, 11:18:16 AM »

Hello,

Just finished installing the upgrade. Sounds wonderful! More of everything and smoother to boot. However, I now have a slight imbalance between channels with the left being quieter than the right. I've swapped tubes, cables and changed sources to no avail. All of my voltage checks were in range except for a slightly high B+ Reg value.

Here are my results:

6U = 130.4V
16U = 135.1V
B+ Reg = 188V
4U = 8.02V
14U = 8.05V

How would I go about measuring if there actually is an imbalance? And where should I focus my attention when looking for the problem?

Thanks in advance,

Todd

Will there ever be another phono amp from you guys? im just a lil curious i personally love your high end headphone amp and would love a phono amp to  match that amp.

We don't have plans to replace the Eros 2 we currently have in the lineup at the moment. We consider that a great match for our high end equipment.

Okay I just tried a different cable. Same as the old one. Right channel coming in a bit louder. But when I plug my phone into the input and play the 60hz tone both channels are equal. Has to be something coming from my turntable I guess then? Maybe it’s too close to my Eros.

Do you hear the same noise with nothing plugged into the RCA inputs?

Eros Phono / Re: Slight channel imbalance

I put a ruler on my screen to try to look for the imbalance and I wasn't able to see it there.  I think you should start by playing a 60Hz tone into the Eros with a different source and measuring the AC voltage at the output jacks.  This is a little hard with step-ups since the typical sources available like old phones and tablets with 1/8" TRS jacks will tend to put out a little too much signal at lower levels, so you may have to get a bit creative on that.  This is an important step, however, as you'd want to narrow things down to the Eros itself. 

Other tests to do would be to swap the incoming channels and recheck, swap the outgoing cables and recheck, then swap the EF86s and recheck.

After messing around with the interconnects, I’m pretty sure the problem is the cable that runs from the Eros RCA out to my Scarlett 2i2 1/4” input. The imbalance followed the red/right channel cable. Strangely the imbalance is only present with the turntable connected. When it’s just the Eros connected to my interface the balance is almost perfect.

Edit:

Oh yeah also I played the 60hz tone and the balance was almost perfect. Varied slightly but only within like 0.2dB.
