Half of a ECC81 is EC92, for info. I bild a phono riaa, passive, with half ECC81 in the input, and a half ECC82 or E80CC second stage. With good results, but some ECC81 are microfonic sensible. I tried also a ECC85 as replacement for ECC81, this works fine, but a little less gain. Also, I used ECC81/85 in as phase inverter/ driver for a EL84PP amp.
