Video how to bias vintage modern!!!

[GIZMO]

hello to everyone
well i decided to made a video showing how you can adjust your bias in the 2266 or 2266c it's the same thing........sorry for my english i'm from athens greece so you know.......at least you can get a picture from inside the amp ...
i really wish my video to help you learning to adjust the bias on your own...it's very easy...
thank you and sorry again for my bad english..... enjoy!!!

Well done Gizmo! At least your english is better than my greek!

Great job Gizmo, I think your video is very easy to understand. Your English was good I had no trouble understanding you. Thank you for taking the time to do this. I will move this post over to the FAQ area later and "sticky" it

Again thanks

Very good!
One thing I did to make it much easier was replace the two lines from the meter from the post kind (like you have in the video) to the clip kind. That way I can make the connections without worrying about slipping and touching something lethal.

Great video! Looks simple now that I've seen someone do it.

Thanks! I'd definitely like to see a video of the 2466 being biased.

The 2466 biases the same way, only you read both tubes (2 per side) through each pin. The Mv reading would be for both tubes on one side, so it will be higher (75-80 according to Steve D).

Nice job on the video - I commented on youtube that you sound like Yngwie giving a lesson!

The 2466 biases the same way, only you read both tubes (2 per side) through each pin. You need to double the Mv reading (90 or 45 per tube).

hey .....thanks a lot guys i really like that you enjoyed the video....as far as sounding like yngwie i agree......... ...

The plate voltage is higher on the 2466.

The 2466 should be biased to between 72 to 80mV per side ('90 or 45 per tube' would be too hot!!)

A very good effort GIZMO but my heart was in my mouth when your hand was hovering over those screen grid resistors. :scared

By the way your English is pretty good but I feel I must let you know that 'chassis' is pronounced like 'gassy'.

[GIZMO]

hey Steve thanks for your kind words....i know my english sucks but i'm trying...if i died touching those resistors at least i would be a dead fried rockstar... : something like fried chicken you know....

anyway i have a question for you if you don't mind....when i biased my VM i noticed that i had almost 2mA difference between the 2 tubes i'ts ok that? i think the stock tubes are pretty well matched.....how much would be the biggest difference between the 2 tubes if it is not matched?

thank you

Indeed, very nice video. I was going to make a biasing video but you beat me to it. Well, if it's found necessary to have a 2466 bias video, I could do that.

One thing I'd suggest adding, is if you use the speaker as a load while biasing, be sure and turn the master volume to zero to lower the possibility of noise issues while having the chassis out of the wood.

Ah, higher plate voltage on the 100 watter. I wonder if that results in a different feel /tone? Thanks for the correction - I wouldn't want to blow up people's tubes!
