Looking for info on how to convert to an adjustable bias.

If you don't already know, you probably ought'nt try it yourself. If you get it wrong, you can really screw the pooch. You're basically replacing a fixed resistor (or series of resistors) with a rheostat (variable resistor) or potentiometer (voltage divider).
Look up Monsta-Tone on this board. He's a great tech and he converted my Mk. III to variable adjustable bias and did a great job. Can't recommend him enough.

it is just better to order tubes and let the vendor know it is for a recto and you want them to have a hotter bias. Honestly y ou dont want to get the bias too hot on the recto's as the primary distortion is pre-amp, when you start mixing the large amounts of pre-amp distortion with power amp distortion it really does not do the recto well. But in hindsight you want to have the tubes a little bit hotter then factory so this way the bias is not to low.
