   Dear list,
   Looking forward to apply the oven configuration of the 10811 oven oscillator - that is working so well - could you please help me identifying the appropriate references for the active parts :
   Q7 and Q8 heating darligntons PNP
   Q4 driving transistor PNP
   U1 and U3 op amps
   From the schematic on fig 8-15 on page 64 of the HP manual.

   Thx very much,
   Gilles.
