Download not one but two circa ’72 brochures for the EMT 240 ‘Gold Foil’ reverb system:

The 240 was apparently intended not to replace the 140 so much as provide a smaller, portable (132 lbs haha) alternative. I’ve provided y’all with 10 pages of documentation here, it’s worth reading.. this thing really is an engineering marvel. Rather than a ‘plate,’ the reverberant surface is a tensioned sheet of gold-foil 18 microns thick. This gold-foil material, btw, was a completely in-house-made material… fkkn crazy. Anyhow, check it out… those of you who have had experience working with both a 140 and 240, pls weigh in on the relative merits thereof.
