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...
When threading tape, it is somewhat easy to accidentally twist the tape so that the oxide side faces OUT instead of IN. Also check the play head surface with a strong light and a jewelers loupe. Look for 'brown stuff". Every time before you play a tape the heads should be cleaned. However...
Not sure why you are referring to only one fuse. I said there was one fuse for the power line and two secondary fuses for the voltage regulators, so three. And I indicated where they were and how to determine the values. (you look at the label next to the fuse to determine value)
I have not...
All the information you need is right in front of you . See the top photo? That sign is for the main power line fuse.The sign says to use a 3.15A fuse if your power is 120VAC and use a 1.6A fuse if your power is 220VAC. You didn't say what power you have so we can't tell you which fuse to...
For "Tape Project tapes", your deck has the wrong speed, wrong track format and wrong EQ. So just sell it and buy a deck that is compatible (15ips, 2 track and IEC EQ). Even better is to get a deck just for the transport and then add an outboard play amp to it. Good choices for a 15ips/2track...
Doesn't matter if the deck was rebuilt. If you can easily hear the difference between source and tape, then it was not calibrated properly. Simple as that. Unfortunately there are few techs left that really know how to align a tape deck. The demo you heard does not represent the capability of...
You have to remove the "amp block" to access the pots. See pages 5 to 7 of the service manual for instructions. I assume you have the manual. If not, go to HiFi Engine to download.
This speaker review just posted today! The reviewer explains why, in his opinion, omnidirectional is the best dispersion pattern (assuming it is implemented well, of course)

I assumed the owner has already tried (without success) to re-position the speakers. Changing the tweeter level is a very reasonable thing to try and is very effective. It is not making the speaker inaccurate at all. Many manufacturers (like Wilson Audio) have user-adjustable tweeter levels...
I would reduce the volume of the tweeter by modifying the crossover. I have done this to many of my speakers and it's always an improvement.
Many high-end speakers do have tweeter level controls.
