Thanx for replay.

In Poland there is 220V wall voltage.

I did a bias in my OR120. There was 450V (low!!) plate voltage and 42mA bias that's why my OR burned quad of Svetlanas. I biased the amp on 37mA starting at 33mA and listening how it sounds. 37mA is point where my OR sounds best. And now the temperature is much lower. What do You think of so low pla...

Thanx for replay.
I found another mod that could be easier and not that invasive.

I would like my amp to sound more dynamic and a little brighter.

Do You think this mod will do this?


Thanx

I have a question if it is possible to make a "Mod no2: Opening up your tone" ( [http://users.telenet.be/orangefg/orange_mods.htm ) in my OR120 "Master Volume" reissue from 1995? I want to suggest my tech to do this mod to wake up my amp.

Thanx for help. Now I know the history of my CITRONETE

What year is my OR120?
