Default RADFORD - Low Distortion Measuring Set

I badly want a distortion analyzer and I found this thing a while ago. It is still collecting a lot of dust in a pawn shop and I think I should buy it, even just for heck of it. I looks to be mint condition and I could get for $50.

It is a Radford LDMS2-2 and the meter indicates distortion meaurment to 0.03% full scale. I think it would be a suitable piece of kit for a beginner like me? Made in the UK by, I believe, the same Radford folks that built amplifiers? Did they even sell these things or was it for Radford use internally I wonder?

It runs off two 9 volt batteries! I could change that easily? I guess it was portable but I don't know why.

Does anyone have a manual for it?

Cheers,

Shawn.

Thanks Trev, the Radford looks great but if it doesn't work I'll need a schematic...perhaps there is one inside?

Still tweaking the DC300A. It should be tip-top very soon.

Thanks for the link! I had some corespondance with that chap a while ago when I first saw the Radford a few months back. He directed me to one of the engineers that worked for Radford but unfortunately I never could make contact with the guy.

Thanks for keeping an eye out. Perhaps someone out there does have some info?

Cheers,

Shawn.

Default Big 9Volt's

I don't recall 9Volt batteries every being so large. Pretty cool. I'll try it out on a few 9 volt batteries to see if it works.

Red face Radford Batteries ...

Battery Data - These 276 are pretty hefty, so those small ones might last very long ! Good enough for a "dead or alive" test though !

Good Luck !!!
