Hope you get this msg - some engineers use several freq's to bias a tape. They find a similar level for various freq's instead of overbias method. Are you familiar with this procedure ? Is it a common level after the bias peak point ?

Why would you do the input after everything else? Makes no sense

Great tutorial, but the audio is way to low.

Don't forget the bias adjustment

Yeah it's completely aligned if it were a 1 track machine. 23 more to go. Thank you for a good alignment demo though nicely done Ken.

Useful video. However, you failed to mention at the beginning that you need to do those steps for EACH of the 24 channels. Some of your viewers may become confused at this. I did hear you mention that it does need to be done for each, but it was quick, and you were mumbling. However, like I stated earlier, it contained some very useful information. Thank you

Thanks!

Hi !!! I Have Otari MTR 90 Mk I , All Machine work good All function Good All Buttons and Lights Good ,But No Play Mode No FF No Rew Mode, Capstain Voltage 0v, Disconect Capstain motor test from adition Power 4v DC motor Work Good,Tester no motor 36v Play Mode 36v FF -36v Rew, conect Capstain motor Again 0v on the motor, Tech good 90 Degree 5v Sine wave good Squer wave good,Flip Flap good, Reels Motor good Tension Good, Motor Amp All 3 good ... Wath You Decision ??? Please have any Idiya ?

Great video thank you for your experience and time!

"And the machine is completely aligned now". No, it isn't! Only track1 is aligned! :P

input cal should be done before record level cal or you get level mismatch on the tape otherwise all the steps are covered correctly. I would have done in a slightly different order but close enough :)

Cue repro should really be set up after record align for a more accurate cue set up. if you record tones after record align and set cue to that it will be more accurate during overdubs and punch ins.

The machine should always be cleaned but I would be careful with de mag. If you do not know what you are doing you can magnetize the head more than de mag it.

good!

Great info,,, need i it!

Thanks for the valuable info mate! :) I will be using this info soon! ;) By the way could you talk a little about damaging heads? Do you do it frequently?

What semester do we learn this in?
