Описание к видео Soldano SLO 30 : How to bias check amplifier when replacing the power tubes (2023)

For guitar amplifier technicians and electronics repair personnel...this video is educational only.
Do not attempt to measure voltages or repair an amplifier if you are not qualified to do so. Internal voltages can be lethal.

NEW TUBES : Sovtek 5881WXT, matched pair
Plate voltage ~ 430VDC (approx)...measure @ pin 3 of each power tube
Target Bias range ~ 34mA cool 60% ~ 37mA median 65% ~ 40mA hot 70%
Measure bias across R63 & R64 1-ohm resistors) with meter set to 200mV DC voltage range, 1mV~1mA
Adjust VR12 bias trimpot to set desired dissipation.

Recommend watching on 1.25X - 1.5X speed...I am from Texas so I talk slow as hell, sorry!
