Wanted: B&K MC101 or B&K Pro 10 preamplifier

Looking for a B&K MC101 or Pro 10 preamplifier. Does anyone know if the B&K PT3 or PT5 are as good as the MC or the Pro.
I have a B&K ST 202 amp and Vandersteen 2c speakers. I am on a budget putting my first system together. The MC101 and Pro10 are hard to find. Thanks
Hi pd777,  I'm not sure if you're still interested but I have a B&K MC101 pre-amplifier available.  I took it out of service about 18 months ago when I upgraded my entire system.  I am the original owner and it is in the original box and is in excellent condition for its age.  I used it in conjunction with a B&K EX442 amplifier (which I also still have) and Legacy Signature speakers (also still have). I'm not sure what it's worth but it is still a very nice pre-amp.  Let me know if you're interested.  Thanks.
