Does anybody here use one of these? If so, do they work well? I'm thinking about picking one up, it seems like it would make the amp biasing process pretty much foolproof.

I have one and it is well worth the cost. The only thing I don't like about it is the bias sockets are a little tall and you won't have enough clearance to put a tube in the head without removing the chassis from the head shell.

I use one all the time..Most amps have to be taken out of the headshell to get to the bias trimmer. If your amp has bias adjustment on the back panel of the chassis.I believe you can order the tube bias adapter socket for that type or whatever??
The Right Angle Adapter allows one to bias a typical BF head without removing the chassis. The Angle Adapter is plugged into the socket, the Bias Rite head is plugged into the Angle Adapter, and then the tube is plugged into the Bias Rite head. The angle of the adapter is oriented for Fender amps where the space between pins 1 and 2 of an octal output tube socket faces the rear of the chassis. A different orientation may be specified on special order for no extra cost. Simply specify where the socket keyway is in relation to the rear of the chassis. For instance, if the keyway on the socket is facing the front of the chassis, you would specify 12 o'clock orientation. Also specify whether the tubes are mounted normal (Marshall, etc.) or upside down (Fender, etc.).

+ 1 on the Bias Rite
Get one,go to a local amp fest and you'll become everyone best friend(dude,can you check my amp for me?).
Only one time so far have I ever come across 2 quads of tubes that came up with the same mA rating (didnt have to adjust the trim pot). So this has become a tool I couldnt live without.
I got mine used off of E-Bay a few years ago for under $100.00

This is the one I am going to get. Tells you everything you need including the plate voltage.

I like the Bias Rite BR-4, which i use for biasing my amps.. Makes the process very quick and easy!!
I have used various other biasing methods over the years, but the Bias Rite is the quickest, simplest and also safest IMO.

I'll +1 this. I sold mine, but I'd get another if I had amps that needed to be biased.

I believe that I witnessed your Bias Rite in action at the Cleveland ampfest. It as pretty cool to see how that works. I have a RM50 coming in the mail so hopefully I will just need a multimeter to do my biasing from now on. ROCK.

I picked up a bias rite. At $125 it won't take long to pay for itself. Thanks for all the opinions!
