Not like you to be divulging secrets Matt ;D

No transistors but there will be a diode, a capacitor and an Silcon Controlled Rectifier(SCR or Thyristor) in there.
Should be able to see the cap with a analogue multi meter on the Ohm scale.Not sure about the SCR but.....
Good luck as you will need it. :D
