Have 3 of 'em...one boxed/new from eBay a few years back...overpaid
for that - they go for peanuts now
Originally bought one in 1971 - used for 15 years until a Meridian 104/
JVC TX-900L.
The Stereofetic is capable of superb results (ie, typically in advance
of the quality now transmitted - especially in terms of transient
response).

It has a few weaknesses.
The stereo decoder needs tweaking - top LH underneath decoder board
pot - as 'mono' is differentiated from 'stereo' by little more than a
2/3mm turn.
The power supply can fail - and capacitor Hum can be around from this
source.
You might get a bit of noise from the aged transistors.
The capacitors (1.5/10uF) definitely need either replacing or
bypassing.
The output leads are pretty awful quality - thin OFC is far better.
The tuner has an inherently somewhat 'bright' response...although
essentially more 'neutral' than the preceding Stereo Troughline 3.
I needed to mod a Meridian 104 quite a lot to achieve the 'speed' that
the Stereofetic is capable of.
It should be quite sensitive (there is a bit of pot-tweaking that can
be done underneath the gang's) - but the wide-ish IF is possibly not
suitable for crowded City locales.
