Hi all. I took the plunge recently and ordered a short MRL tape to align my ReVox B-77. It had lost much of it's sonic luster lately, and I wanted to verify all was OK. Aligning the playback head (physically) revealed no major problems. However, I was very surprised and shocked to discover that the record head was off quite a bit in terms of physical alignment. What I did was this-I put together a test tone CD to feed the machine 12k, 16k and 20kHz signals-I used this since I do not have a frequency generator at my disposal. Anyway, turning the azimuth screw of the record head slightly clockwise, I discovered that the VU meters literally took off! I played the 20kHz tone repeatedly (at -10 or so) until I found I could do no better in terms of signal strength, and checked record vs. play results each time. Last night, I recorded some big band music at a local dance on the lake, and the tape sounded fine this morning. What a relief! My question is, does any one know what to use to hold the physical alignment in place at the set screws for the heads themselves? I have what appears to be (broken) LocTite on the screws now. It is red in color. I believe that simply transporting my machine to and from rehearsal each week over a 2 1/2 year period is responsible for the physical alignment being thrown out of whack. I want to lock these down good so this does not happen again. When I did the last machine alignment at ATR Services in 2005, LocTite was not used to hold the heads in place. Nothing was. I learned my lesson! Anyone know which specific LocTite I should use, and where I can get it? Thanks in advance.
