    Head groove-o-mania

    My first interaction with the lovely 220V was at the age of 2! Since then, I had many intercoarses with different kind of voltages (from 50V to 2kV). The worse was a rectified short of 600V, I was stuck there and saved me the safety features... Anyway, Vince, this is more than serious. I know a...

    Head groove-o-mania

    Vince you had much patience with the pathetic moron, there! When I returned to the analog sound and bought my first deck, a Technics RS-BX606, I had already done my homework to make it run properly. Go figure, the deck cost me 40€ and the tools to service it (including test tapes) over 400€...

    Head groove-o-mania

    This was the story of my Technics RS-BX808. Someone had messed with it's head tilting and height and they had adjusted accordingly the electronics to counter the losses. I was suspicious of the relative "low" price but I bid on it knowing how easy it's to repair these decks. The head was so wear...

    Head groove-o-mania

    @vince666 , I agree. I'm just seeing it from a different point of view. The available decks are getting older. No more are produced (yeah, Teac I know. C'mon). So, it's logical wear adds on them. The point is to distinguish when that wear is tolerable or it is over practical use. A photo of a...

    I see... You have to show me a photo, first. No photo, no head wear. (just head scratching... :p)

    Head groove-o-mania

    You are right. In simple words, can anyone safely condemn a head because it has a groove? Any kind of. I have seen people to say "this head is crap" in the slightest view of groove.

    Head groove-o-mania

    I have seen that there is a custom among the cassette users community to condemn a head that has a groove. Ok, it's obvious that wear isn't favorable for the head performance but where is the limit? Not all the heads with wear are off. I have seen the groove accumulated on new heads after about...

    Channel switch over in different mediums

    Listening a 45rpm single of a favorite song I discovered that it has it's channels switched over to the CD version. And it's not the first time I came across this situation between different copies of same songs. Why should a label confuse the channels of the same song and not follow the...

    Adjusting signal with resistor

    I'm with you on this: most important is to have correct levels at the Dolby chip to make it encode and decode the noise reduction as it should. Everything else beyond the Dolby chips (and dbx in our case) is just a matter of amplification. Now, if Matsushita had the Dolby level wrongly...

    Adjusting signal with resistor

    Edit: sorry for stating my 965 gave me 545mV. Now, recalling, I think I didn't bothered to measure the outputs on these decks since I bought them last and I was always confident that they give the same as all the other Technics I had calibrated so long...

    Adjusting signal with resistor

    Update: I was curious about the above so I replicated your mod. Yes, it makes no difference. My levels are the same with either the ne5534 or the njm2114. More interesting: I recalibrated my decks with ANT's test tape and I took these interesting measures: RS-TR333 (x3), RS-B565, RS-B655...

    Adjusting signal with resistor

    Indeed, there is nothing between trimmer vr3 & vr4 and ic5 & ic6 inputs to be a problem. So, if you have 245mV at Dolby then the level arrives correct at njm2114 (ic5 & 6). I'm not an electronics engineer so I can't calculate the impact of the resistors removed, on paper; I go try and error...

    Under - biasing on purpose

    Vince has been helpful to me a lot of times, I have to admit!!! I don't know which member Sep is, unfortunately! I struggle to learn members' real names since I'm new here! I appreciate the interest all the members showed, here!!! I was quite afraid this could be a silly question but I was...

    Live Test - Analog VS Digital - A REAL test

    I can't follow a 2 - hours conversation about digital vs analog. I have my own experience. On the other hand, it's ok to hear other people's opinions. Perhaps, you can learn some new things. But always, the final judge will be my ears. One thing is for sure: trying to judge an analog source...

    Under - biasing on purpose

    I usually do not intervene in original EQ. My POV is that the artist/producer knows better. If I have to alter EQ, I would use my Technics SH-GE70 which has a tape loop chain connections unless my format is digital so then, I use a computer (and Steinberg's Wavelab). I wouldn't consider to use...
