Counterpoint SA-3.1 and 5.1


I never see these pre-amps available. I remember them as very easy to listen to while having quite a bit of detail. Are they all dead or is it that no one wants to part with them?

Does anyone have the full tube complement for the SA 5.1? I'm thinking of pulling it out of storage and hooking it back up. Since Altavista shut there doors, I cannot find any info on these preamps! Thanks
all info is from the Jan 2014 site is Here:

SA-5.1 Uses two 6DJ8 types in the phono stage, two 6DJ8 type in the line stage, one 6CA4 type, one 5651, one 6JC6A and one 6GC5.
Anyone here still using 3.1? I just got one myself and im wondering if i can use the line out  as a regular output like the main out? If im getting it correctly you can use that if the source you’re using has a level or volume output... ?? The line output will bypass the 3.1’s gain mute and balance???
