Hello all! I am still looking for a lid for my 4.2. I'm afraid to take it anywhere without one! Here is my machine: Here is a lid on ebay... Question: even if I were to find the hardware for this lid, am I correct that this is for the dual push lock, whereas mine requires one with the rotary latch? Thank you very much

Thank you for clarifying that. Indeed I did not understand what the capstan O ring was!

Thank you so much for your comments Dela. This has all been very good to read.

Thank you for the response! I'm very glad that you told me the lids are not interchangeable. I also appreciate your answers, those were very helpful. I think I have a rubber pinch roller, and the motor runs nicely. I have opened it up actually! I will add those pictures at the bottom here. I've been told my mic preamps are QPSE and QPM 3-5 (but missing a piece...) - do I have any options when it comes to getting 48V power for a condenser mic? Lastly, if anyone can recommend good new tape to buy, I would be grateful.

Hello all, Sorry for my delay. I recently got a 4.2, and I love it! But I would greatly appreciate some advice, as my knowledge of tape is very limited. According to the serial number lookup, my model is from 1973. I read most of the 1991 manual upon purchasing and learned some, but not all. 1) What kind of tape should I buy?! Is it bad to use old tape? 2) Is it bad to have the tape up against the heads all the time? In other words, each time I wish to take a day+ break in my recording, should I fully rewind, and upon coming back, FFW to the part of the tape I left off at? Surely all that FFW'ing can't be great for the heads? Alternatively, I could open the pinch roller arm during storage, but the manual said this would cause a flat on the Capstan Shaft O ring. (That does not make sense to me... I'm including the relevant passage from the manual.) 3) With my purchase, I was given the power pack pictured. Can I be sure that this power pack is sufficient? The manual mentions the danger of a reversed polarization supply. Can anyone say whether or not I'm good to use the one I was given? (Speed and power indicator DOES show a white segment and machine APPEARS to function perfectly when I use this power pack.) (I'm including images from the 1991 manual.) 4) I have observed that my 4.2 looks different than later models. Different knobs, no playback head shield, different lid latch I think? Is there anything I should know about having a '73 model specifically? How else does it differ from the later ones? 5) In general, do you think I got a decent specimen? 6) Does anyone have a lid they'd be willing to sell?! If you don't mind I might ask a few more... thank you very much for helping me out. Here's some nice pics in return! Here's what they say about the capstan shaft O ring: Here's the power supply info: Same thing again: And the danger I had mentioned:

Hello all, I am currently gathering some questions to ask about my first Nagra. (4.2.) Should I post them here or start a new thread? Nice community you have here!
