eXStatA Build Thread II - Page 39

post #571 of 581

So I'm the one who was fortunate to get this unit from loserica. As of now, I haven't touched the internal wiring of the amp yet. The amp is now functional with the SR-404LE despite not being rewired for 120v. Is there something I should worry about, as far as safety and performance go?

I think it is VERY important to set the proper voltage!! There is a risk of burn something using the 220V setting, instead of 110V!? Personal, I wouldn't risk using an improper voltage, I don't think it is safe. :rolleyes:

We waiting for other opinions. Thank you.

Sorry for my diagram.

I thought the US was on 110V.

Separate the Brown and Black/Red wires. Tape the ends for safety.

 

Disconnect the Blue/Yellow wire from the power inlet. Tape the end for safety.

 

Connect the Blue and Black wires together, then connect the pair to the Line connection on the power inlet.

 

Disconnect the White wire from the power inlet and cut off the connector.

 

Connect the White and Brown wires together, then connect the pair to the Neutral connection on the power inlet.


Thanks funch. I changed the wiring with minimal issues. The amp is now functional at 120v.

So I have been having a minor issue with the eXStatA and SR-404LE system and I hope I can find an answer here (I'm still new to the e-stat world).

I normally have the source and the SR-404LE plugged prior to powering on. When I turn the switch, I hear a moderate screeching (more on the left driver) for 3-5 seconds before it dies down. I can hear music throughout the whole process. I'm wondering if it's an issue of my rewiring or my power condition. I'll take a picture and upload it when I get off work today.

When I searched eXStatA build thread in the past, there was one mention of the screeching issues but it doesn't seem like the origional poster posted an update.

Thanks a million.

Just sounds like the tubes powering up. You might try leaving the 'phones unplugged until the tubes have warmed up.

My eXStatA is a solid state built though. biggrin.gif
post #578 of 581

Ah, I stand corrected. Still, try leaving the 'phones unplugged for a bit after turn on, until things stabilize.

post #579 of 581

I see. And by stabilize, do you mean for the amp to finish warming up?

I tried it that way today and there was no screeching but then I had some static from plugging in the earspeakers. I guess I can't win it all.

post #580 of 581

Static indicates dirty or slightly oxidized contacts. Use some contact cleaner very sparingly and see if that helps.

Thanks funch, I'll try it and report back after work.
