I asked John French of JRF Magnetics about that situation and he said the result will be about 1 dB more noise and mentioned nothing else. That sounds pretty harmless.
I never said he directly denigrated Studer and Ampex engineers.
I was just making comment on his foolish belief that:
"how chasing specs like minimizing W&F can actually hurt the sound quality".
One way you can get into R2R is by recording you own mix tapes using Hi-Res streaming (like Tidal) as a source. Buy a 2 track stereo deck and record at 7.5 IPS using new tape like LPR-90 or MDS-36 tape. Here is one for sale...
All three motors in the BR20 are definitely driven with a DC voltage. I have measured those voltages on numerous occasions. The level of the DC voltage going to the motor is regulated by circuits. Inside the DC motors, the voltage is directed to different coils via a type of switch called the...
Stay away from Memorex tapes. You say you want "the best", so go to eBay and buy new, unused Maxell tapes. One of the best Maxell would be their MX 90. Here are some for sale. You never said price was a concern...
You have to expect that the shipping box will sometimes be dropped off a truck or off a conveyor belt. The B77 can be packed in such a way to prevent any damage from such drops and my guess is that your B77 was not packed properly.
Perhaps both. A friend once installed double drywall on his listening room walls to prevent loud music getting to other areas of the house. He claims his bass problems became worse after that. Perhaps the walls were more rigid and reflecting bass rather than some absorption due to flexing.
Don't be all that worried about getting the so-called "optimum room dimensions". Acoustician Dr. Floyd Toole says the golden ratios only work if you have a speaker in one corner and your ear in the far opposite corner. If you move your ears or speaker to another location, the ratios get thrown...
No need to. The field from a demagnetizer will not hurt an amp, preamp or Turntable. And if you keep a demag unit 12" away from another deck, there is no concern.
The highest quality/most powerful demagnetizer is made by Annis (the Han-d-mag). They recommend 12" distance from heads when...
The world's leading expert on tape decks has said that 3 inches (~70mm) is all the distance you need before turning off the demagnetizer!

When demagnetizing each part on a headlock you can slowly move the demagnetizer from part to part...
