All were apparently unused. Those are old special quality (SQ) types that tend to be less microphonic than the ordinary EF86 types. the EF89 looks like it might be of interest for a compressor/limiter. Was macht diese Röhre so besonders gegenüber einer ECC83? Very similar electrode construction, with an overall screeening shield but the EF80 oddly has a taller envelope despite the internals being somewhat smaller.
