I was doing a search on my shop for a 6BA6 tube that a friend is looking for and I've find a pair of 6SK7
so I recall I've seen this tube used as PI in an amp present on a thread of our friend TIMBO

With reference to this other thread

where was discussed about the use of the 6SK7 as tube compressor I was wondering which will be the effect of the 6SK7 as PI like in the
schematic that TIMBO posted, where the circuit isn't optimized for compression purpose

Also, if I've understand correctly, a remote-cuttoff tube is hard to drive to cuttoff so ....
if I use a 6SK7 as V1 (instead of 6SJ7) in a circuit like the 5C1, what will happen ? Will this give an amp with more headroom ?

Since the input voltage is quite low at V1, having headroom is never really an issue unless you are driving it hard with a pedal, in which case, it is likely that you want the stage to clip anyway, so having a remote-cutoff tube in that position kinda defeats the purpose.

Right, thanks for answering, I've just realized that was a stupid question
