Avalon U5 need power LED

[pucho812]

Hi! I just wanted to share with you my experience repairing this piece of equipment. From one day to another it stopped working. I am in EU so the mains switch was set at 230V. I switched it to 115V and conected it to a 115V autotransformer and it worked! So I guessed that one of the primary windings was open. Once I put a new transformer, the unit didn't turn on. Well, some audio was passing trough but the power led wasn't lit. So, as Pucho812 said:

That was it. Once I secured the connections, the unit was working again!

Nicely done. These units sound so good as a DI it would be a shame to not have them working.

Hello,
Ive got a similar problem, U5 with distorted audio and no power led, switches (were) working.
I checked transformer secondaries which were ok, then I found C11 being open circuit.
Replaced it and when powering on, R50 burnt out... So C11 may not have been the main problem.
Then I removed C11 completely and switched on again, not a good idea, now R84 was burning...
So, can anyone help me out? I also need the values for R50 and R84.
Thanks!
