    It's good to see you here, Bob!

    The big low-end bump might be from the current headblock. I see the bump in both IEC and NAB EQ @15ips. The plan is to send the spare headblock with major wear to John French for relap. John think these C37 heads can be significantly worn but he can still lap them. I am also hoarding one set of NOS record and repro heads for it.

    During the rebuild, I had to buy five more pushbutton contacts from Europe to fix the broken Stop and Play buttons as well. I still have few spares.

    I am surprised at your bad A80 experiences. Are you referring to A80VU or A80RC model?

        I think it was an A-80VU.

          Other than sharing same electro-mechanical transport section, A80VU and A80RC are quite different in my opinion. For audiophile use, the A80RC is more fitting for having higher inductance repro head (~10mH on VU vs ~200mH on RC) and simpler audio electronics with all discrete components.

          I think a Studer A80RC Mk2 with its repro head direct wired out to feed an external tube tape head preamp could out perform a C37 technically (and not to mention in reliability aspects).

          However, nothing can touch C37's coolness.

              I know myself well enough to know that I can't get pulled into collecting tape decks. Well at least not right now.

              I sense though that Andre is weakening. I hear TAS is going to buy Andre a UHA deck!

              I've stayed away from the potato chips for the moment. Besides, here in my part of the country, it's Grippo's potato chips.

              BTW: I'm pretty sure there will be no UHA deck coming my way. That must be for someone else.

                      HI Andre,

                      Hope you & the family are well.

                      For someone that has deep roots in analog, you really need to make this step!

                      Of course you already know this!

                        Hello Ki.
                        Great work on your Studer!
                        I also bought a C37. I replaced all the electrolytic caps(Rifa), the bearing(SKF E2...) and the head cables( Mogami).
                        The machine is now running very good, but the capstan motor makes some vibrations (you can feel it on the deck).
                        Do you also have vibrations from the motor? Have you changed the motorcap?
                        And why did you change the mustard caps? As I realy want to know all the "secrets" about the machine, I hope you can give me some Information....
                        best regards,
                        Markus

                          Markus:

                          Sorry I didn't get here until now and saw your question.

                          First of all, the vibration you feel and hear from the capstan motor is more than likely from lack of oil. If the machine had been resting for many years, it didn't get its annual oiling. You also need proper organic oil and not the synthetic kind modern Studer uses. I had the part number once but can't recall now. You can do Google for C37 capstan oil.

                          Other than signal caps in the audio chain, all the electrolytic and film caps have been replaced - more for safety and longevity reasons.

                          Ki

                            I dissambled the capstan motor, cleaned it and it got new oil. Studer recommends DTE-EH Oil ,and I took E NUTO 150, which has the same spec.
                            At 15 IPS you can feel the vibration. It is not that i hear it so much. Twisting the coupling rubber decreased it a little bit.I thought changing the motorcap, 3mF (maybe to 2,5mF..) would smooth it...
                            I now that a AC motor vibrates, just wanted to know your experience to compare.

                            Hi Markus:

                            If oiling and filling the oil reservoir with oil didn't remove the vibration, I would suspect your capstan assembly needs new bearings. Did you check the bearings when you disassembled the capstan motor assembly? My capstan assembly got new bearings and it is quiet and vibration free close to other far younger Studers in the house.
