Does anyone know any other type of transistor to replace this difficult to find Ac151 r Vi ?

I would try the version without "r" (you will get more bad signal to noise ratio, but in an extrem small amount).
Very important is the fact, that you must use a genuine Siemens NOS version like from the follow auctions:
AC151(V) GERMANIUM TRANSISTOR | eBay
AC151(V) GERMANIUM TRANSISTOR | eBay
AC151 Siemens Germanium Transistor Fuzz Pedal NOS AC151/1 | eBay
Versions from other brands are mostly not helpful.
