VHX Bias

[Raider-X]

@Leo Diezel -- Hey Leo -- quick question -- where is the trim pot to bias the VHX? Had a fuse blow yesterday and I suspect it's time to change the tubes -- they've got around 3-4K hours on em at this point. I read the manual on the Diezel website but it does not include the VHX...

Thanks ~~

I've read some of the diezels had auto bias or something in the menu -- I didn't see anything about in the manual or the settings so I assume it has to be done manually yeah? Thanks for the quick reply!

It's the one closer to the input jack, no need to bias, you can replace it without worries!
