Eros Phono / Re: Clogged tube adapter

« Last post by Paul Birkeland on November 18, 2024, 05:33:02 AM »

I would get a set of small metal punches and a really small hammer, then gently tap on that with a small metal punch until it breaks away.  I suspect this is glaze for the ceramic socket, and it should break away about like glass would.

Eros Phono / Clogged tube adapter

« Last post by maarten on November 17, 2024, 10:12:43 AM »

Hi,

I just reached page 44 which tests the tubes.
I noticed one of my tube holders has two clogged holes. There seems to be some resin/plastic inside.
The tube hasn't really seen any "action" so I don't think this is an accident through soldering -- the bottom also looks intact.
I guess I'll just find the tiniest drill I can and try and drill the resin out. It's quite hard!

General Discussion / left speaker not working.

« Last post by robertod on November 17, 2024, 06:27:34 AM »

I switched the input cable from left to right and now the left speaker works and the right speaker does not.
What should I check out next... Maybe something in the pre-amp, idk.
Thanks
I switched left and right phono cables no help. 
Checking tubes on wright audio pre amp.  Might be a tube.  waiting for system to cool.
*System cooled, two tubes out, replaced.
*System up and running.
**Solved**

S.E.X. Kit / Sub out - like Stereomour?

« Last post by dpwoos on November 17, 2024, 03:57:49 AM »

PJ had mentioned it in the past.  There's a 249K resistor between the 0.1uF brown coupling cap and ground. You can lift the ground end, then solder in a 2.49K resistor between the free end of the 249K resistor and ground.  The subwoofer out can be taken from this node.  I would run a twisted pair of wires from ground and this node on each channel to a pair of female RCA plugs and let them hang from the bottom out the back of the amp just to test this out.

We just did this mod to a Stereomour, and it works great. I recently completed two S.E.X. 3.0 with C4S, and would like to also add subwoofer outputs to one of them. Is it a good idea to do the same thing as we did to the Stereomour? Thanks!

You are missing some parts on your power supply PC board.

Found it. I overlooked that step probably ten times going back through my work.
vDC tests right. Thank you again

Thank you.
I did powder coat the plate, but I also cleaned it with a drimmel and acetone wherever a metal part contacts it--bare metal on bare metal.
