AFAIK the 200 series modules fit into the 200 series, 12-slot rack (API L200R). Whereas the 500 series modules fit into the 500-6B Lunchbox.

Yep, the 212L is part of the 200 series and is of a different size. No luchbox for the 200 series that I have seen unless it as a DYI thing. If you now have the API 6B, then you'll want the current API 512C or any API or compaible 500 series module, and there are now quite a few to choose from that are not made by API. Call back and explain, and they should be willing to take back the 212 for the 512 for the price difference.

Probably didn't waste too much of your money, as they are pretty desirable and someone will want to buy them; but yes, you should smack your friend who gave you the advice. Or do your own product research next time before you make a major purchase.........

And you should know the 212L, 512 and 312 are all identical in circuitry and sound and all utilize the 2520 discrete operational amplifier.

They actually are slightly different...they do use the same opamp, but the circuit layouts are different by necessity, and the transformers are different as well...but they do sound very very similar.

The only difference has been the progression of the Jensen microphone transformer from the K110 to the K115. They changed it from a 10 to 1 winding to a 15 to 1 winding which more changes the output level than the character of the sound and so also relates to a difference in signal-to-noise. The only difference in circuit layout is the circuit board they are mounted on since a 2520 is a 2520 is a 2520 and IS the sound of the API microphone preamplifier. The output transformers are all identical with 3 matching secondary outputs which can be used independently, for up to 3 isolated outputs or, combined to provide different output levels and headroom.

Hmmmmm, Vintage King is usually pretty good with this kind of stuff, who'd you deal with over there?

I'm sure if you explain to them that they sold you two different modules they'd be happy to make an exchange to make it right. 8-)

Yup, Kev, that's the guy. An audio engineer in Wolff's clothing. At least he is not in my clothing!

No Tone Lux yet for me...... Boo-hoo

I thought so,

say hi to him

I hope he is still, not too angry with me ... or my friends
it was a DIY and the old Tech Talk sort of thing
