Hans,

very hard to find, odd frequency, small form factor.
To repair one for a customer I opened the failed oven (on the kitchen 
gas fire, be quick, and the interior does not suffer), decided that 
the original oscillator was beyond economical repair, saved the 5.6 
MHz crystal, built a new oscillator around a couple CMOS gates (the 
original oscillator has a TTL output), added a DB6NT thermostat 
around the crystal, and mounted it all again inside the original 
case. It fits well, and there is no visible repair from outside.
