As the result of a phone call, I now know that the amp uses a 211
preceded by a 6SN7 octal.

OK. Can you also confirm that the output impedance *is* as high as around 8
Ohms - as your quoted DF of 1 implies?

The ELS are later than I thought. Probably 1990? From my description
of them, my BBC pal tells me they are probably type 63 Mk II.

OK. These have a much less 'difficult' impedance characteristic than the
57s. However an amp with an o/p impedance of 8 ohms would still cause a
quite marked change in response as a result of impedance interaction.


They have handles on the side, and were a version for the USA only he
thinks.

Jim, can you confirm this?

I am not sure as I am not a quad 'expert'. but I think that, yes, handles
were something that only appeared on models not intended for domestic UK
useage.

Slainte,

Jim
