Crack-a-two-a / Re: Possible Channel Imbalance

« Last post by XforceVesa2 on Today at 03:03:56 AM »

I can swear that I can hear the Channel Imbalance(Left is a little bit Louder).

Are there any contacts in the Amp that I can measure too to find the "Possible" Problem?

If what's been lost has been caused by introducing the Denon and SUT into the system, perhaps they weren't the best choice. It's all compromise but changing more things to bring back what you've lost by a quite major change to the system can be both costly and frustrating. As an aside, just repositioning the speakers can often bring about useful changes for the better. If you are lucky enough to have a dedicated listening room a rethink on the layout and the furnishings might be useful.

I resoldered every part on the center board and the board above terminals 1-16. Every LED on all three boards are lit up now. Here are the new readings:

Terminals 2,7,13,14,15: 70V
Terminal 4: 107.5V
Terminal 29: 108.5V
Terminals 50,51,59,60: 156V
Terminals 56,57: 136V

Both MJE5731 Transistors are at 106V

The glow won't necessarily be even, and you have healthy voltages at OA and OB, so the tube is working nicely.

Also, there are a number of other threads on this forum which discuss ways to do this. Here's one useful one: https://forum.bottlehead.com/index.php?topic=10243.0

Speakers / Re: Ways to add send signal to a Sub from my stereomour

I connected a REL subwoofer (or, as they call it, a "sub-bass" system) to my Stereomour. REL recommends connecting to the speaker output terminals of the Stereomour, so I did that. So my speaker output terminals had wires going to the REL subwoofer, as well as wires going to my 2-way speakers.

The REL is powered, and has a crossover.

I think there are multiple solutions; this one worked well for me. Good luck!

Speakers / Ways to add send signal to a Sub from my stereomour

« Last post by Agweeks on Yesterday at 12:10:58 PM »

I would like to add a subwoofer my Klipsch La Scalas. With my rock records I find myself looking for frequencies below 50k, especially at low volumes.

I have a Stereomour. A powered sub may be a good solution. I can also buy or build a separate power amp. Any suggestions or examples would be welcomed.

Could I create a signal output from the preamp stage to feed a power amp and crossover for the sub/subs. I am thinking the signal could be controlled by way of a toggle switch so as to easily control when the subs receive a signal or not.

If all of this is crazy talk I’m open to that too; just tell me to keep listening and embrace the limitations of my beautiful sounding system.

So for the short term, some tube swapping seems to have done the trick.

The biggest difference was found by swapping in a Tngsram E88CC for the 6922. A little additional warmth and smoothness was added by trading the EF86 Mullards for some Amperex Bugle Boys.

The unfortunate outcome is that I now know enough about capacitors to be extremely interested and very dangerous

Didn't the old Victrolas use bamboo needles?

12AU7 tubes are relatively cheap, even some NOS ones. There are NOS Sylvania made for Baldwin organs 12UA7 tubes on sale for $12.00 right here for example:

http://www.audiotubes.com/12au7.htm

Much further down on the same page they offer GE organ stock tubes for $9.00. Current production 12AU7 tubes cost roughly the same.
