Moreplay Upgrade / Re: Slight channel imbalance after installing the upgrade

« Last post by heavycowboy on July 01, 2025, 03:52:01 AM »

After measuring the voltage from the output jacks, the difference again was nominal. I'm going to go ahead and blame my aging ears for the perceived imbalance. 

Thanks to both Pauls for chiming in. Again the upgrade sounds incredible. Highly Recommended!

I would put a pair of inexpensive headphones on and run the amp flipped over, then poke around with a wooden chopstick.  Eventually you may find that poking a certain part of the circuit changes the noise you're hearing, and that can help you find loose connections.

I will be building the Mainline 1.1 from what I have read.   

I love the Mainline with Grado's.. the higher u go up the chain, the more the rewards...

You could try Switched-on Bach.

You'd want to turn the volume pot all the way up and see what appears at the output jacks of the preamp while it's playing.

Neothoriator Headphone Amplifier / Re: is this amp still able to be ordered or?

« Last post by Paul Birkeland on June 30, 2025, 05:46:25 AM »

Yes when I read this post, I realized that there's still one downstairs somewhere.  I'd have to fire it up and assess its operational condition, though I don't technically consider myself the owner of that particular unit.
