I used some of these but I quit repairing the series II meters since Joe's work so well.

And they are purdy...

Any pictures of what the new meters look like in an amp?

I'll post a set shortly, she (Beth) is going on the test station after I get done dirtying some more dishes... Man, 2 weeks till the wife comes home.

The meters are hard to photograph because they are so bright and shiny.....

Glen once made a Hemi work in a moped so anything is possible.

Hell anything is doable. Joes meters will not work without a army

Do Joe's meters work like the original PL meters or are they like tape deck meters?

Dual mode, switch selectable. Moving dot or bar graph selectable

Thanks, that's what I wondered. If I ever have any trouble with my amp, I'll have Perry install them. But to just change them out would be cost prohibitive. Shipping's expensive on these beasts, and as good as they look, they're still just eye candy. Really nice eye candy!

First one is the dot mode, the second is the bar mode (which I like best).

OH, AND IT SOUNDS BAD ASS TOO!!!!!!

I guess I was not clear. I this what you would need to recreate

 

[WOPL Sniffer]

Damn, that must be 2 feet long.....

I got the new Bias Transistors in and the bias is now stable and well within adjustable spec for both channels. I have set it to 350mV on both channels.

Now I just need the new meter driver chips to come in, and I can button this up for a while.

There you go

An other success story

With many thanks to you, Perry and Ed. This thing might have killed me (or me it) if I didn't have the help.

Yeah, they're sketchy buggers...

Very impressive. Anyone getting a new build without these should definately rethink their decision. If they had been available when you built mine I would have had them. Not that I need them, but......


Good job on these Joe!

Anytime you want to upgrade let me know. I'll do it for the cost of the White Oak boards. Since it's one of my amps and all.
