Hi all,
I've been scouring the internet to find a cool retro panel meter, preferably one with fairly low dc current range. I've come across a couple of sites that have meters that are passable, but I'm looking for something really retro.
Any ideas?

OK,
Spent a lot of time looking for these and here is the secret -
http://www.fairradio.com/
Here is the direct link to the meter section -
http://www.fairradio.com/catalog.php?mode=view&categoryid=216
I stocked up on a whole lot of (new) retro looking great quality meters at good prices.
The folks at Fairradio don't say much and their emails responses are pretty brief but they post quickly and pack well.
Hope this helps.
Rob

Hi John,
I originally bought a couple of these (if not identical, very similar) from ebay. With no disrespect to the seller, the quality is not great - Chinese made, plastic body and plastic cover and inaccurate. Hence my search for something better.
The ones that I bought from fairradio were only a couple of dollars more (I think they were about $15 US from memory). They are heavy, full metal construction (A&M manufactured - formally Weston) and sealed against the elements with rubber gaskets. The face cover is glass. They look like they might have been made for aircraft instrument panels. They are high quality meters.
Despite the stamp on the back indicating that they should not be dissembled, I pulled them apart, drilled a couple of small holes in the back and added a blue LED to give some back lighting. They look great and I am going to use them as bias meters for an 845 amp that I am building.
I have attached a photo.
Cheers,
Rob

Rob-
Pretty cool-looking.
You were smart to grab those when the price was reasonable.
Getting a matched pair of meters can be tricky at the hamfest...but a good excuse for a lot of wasted Saturdays....
I just use test points and a DMM to check the bias on my tube amps, but I'm 'old school'
Cheers

Glad to help.d1983 said:These are incredible! Exactly what I was looking for!
Please let us know how it works out if you buy from this seller. I'm thinking about buying some stuff from him at some point in the future (the point when I have some cash, that is ).
Cheers
John
Hey Folks ,
Thanks for the comments. I was pleased with the meters.
D1983 - good luck with the meters. Let us know how you go.
Hi John, I test the bias with from test points as well but then use the meters so that I can 'tweak' the bias with the chassis closed if need be.
On an earlier amp that I made, I used digital meters. I can roll tubes and adjust the bias without exposing myself to high voltage.
Couldn't resist attaching one last photo of my digital bias meters.
Cheers,
Rob

I wasn't very clear-by 'test points' I meant pin jacks, accessible from the top of the chassis. See attached pic. (The bias pots are closer to the PS section.)
Meters are pretty cool, though. Very nice job on your amp with the digital meters- slick!
Cheers

I'm measuring the drop across a resistor- the ends of the pin jacks make handy solder points for the (usually 1 ohm) resistors. The 'top end' of the resistors are less than a volt or so above ground in most cases, so pretty safe.Rob11966 said:
Are the test points connected to the high voltage or are you measuring voltage drop across a resistor?
Still, if there were kids in the house, I'd have the top of the chassis enclosed.

A link to pics of my first tube amp which I completed recently. Shows

Hello,
I want to put a meter on each channel of the amp I'm working on but don't know which kind to get. There's AC mA, DC mA, DC A, AC Volts, DC Volts etc.
How do I pick the right one?
Below are links to a couple I'm considering, please let me know if they will work and how to connect them.
AC Volts with Db
DC mA
Thanks.
