Finding J-FETs

[tapepath]

Hello,
Does anyone have a source or possible substitution or data sheet for p-channel J-FET either SPF316 or P1228E. These are used in the input amplifier board for the Revox B77 tape deck.
Thanks!

I am pretty sure that they can be got in an SMD pack and will have to be made up into a blob of epoxy for old style mounting.
My supplier has some very confusing data on these parts and it has wasted me some time.

I appreciate your efforts, thank you.

A 2N5460 was used by Revox in more recent versions of the circuit along with a service bulletin noting the part change.
