Next, adjust the bias control until you have MAX NEGATIVE voltage on pin FIVE. 2016 part number nomenclatura fabricante 1. A comparison was made with a coating mixture of ZnS:Mn phosphor powder and a high temperature clear paint, VHT SP115 (Sperex), on an aluminum foil substrate. The audio is routed from through a coupling capacitor to the end of the Audio Gain control with the arm connected directly to the AF amp grid. I counter disagree, master will not just provide any tone at any volume on any amp, that’s just the nature of tube amps guitar or otherwise. No adjustment necessary. Do high gain amps have NO clean settings? Does a Fender Bassman have a DRIVE knob? The modeled sounds of the amps in my HD500 are modeled amp settings, not amps. Fortunatly, the amp I am working with is the Fender SCXD that has a pair of 6V6 tubes that the bias setting recommended is 40mv read with a DMM at R20 inside the chassis.

Adapters accept all popular octal-base output tube types (6V6, 6L6, EL34, KT66, KT77, KT88, 6550, etc. 0 out of 5 stars 11. VHT Tube Tester + Amp Bias Meter. Goldstein, Pavitra Kumar, Frank C. The bias points for the power tubes are dead-on what's considered to be the "normal operating conditions" for single-ended class A at the B+ the amp runs at (which is 250V), right from tube data sheet examples. 2 to 40 MC Bias series resistor string modified - 600 ohm resistor replaced with 2-300 ohm, allowed moving detector input amp grid connection to junction which slightly increased bias voltage. Weinsheimer, Shantel; Bendjilali, Nasrine; Nelson, Jeffrey; Guo, Diana E; Zaroff. You then need a way of measuring bias current.
