MBL 101 (~1990) - amp suggestions.
This speaker is not that hard to drive; its efficiency appears low because most of the sound does not get to the microphone that is placed only one meter away.You can drive it quite successfully with tubes. But a lot depends on the size and liveli... 
AYRE VX-5 TWENTY- WHICH TUBE PREAMP MATCHS
 I assume you mean by “balanced standard” that there are conpanies that incorporate XLR jacks but that they have single ended circuitry, as opposed to fully balanced designs such as those by Ayre and Aestestix?Actually no. A component can suppor... 
***Is It Me Or Have Todays Modern Tubes Gotten REALLY REALLY Good***
We designed all of our stuff to work with the garden variety of available tubes. Why saddle the customer with the need for a tube that is difficult to get?My experience has been that the Chinese signal tubes are pretty good but for power tubes the... 
Power Amp advice
FYI the hum was not coming through my speakers. It appears to be solved, at least for now, by tightening all the screws I could access without dismantling the innards. I suspect a sympathetic resonance of some stripe. I also suspect it will re... 
Help me rebirth my old turntable
Atmasphere:  thank you for your additional input.  How difficult is it to set up a new cartridge?  Thanks again you have been very helpful.I am certain my local dealer would lend me a better phono preamp, but right now my system sounds a little... 
Reel to reel
This is the tape I'm purchasing;        https://www.atrtape.com/products/mds-36-14-x-3600Now I'm trying to figure what bias and equalization I set on the RS1506 for this tape?If you've been using Ampex Grand Master 456 this is a really similar for...

Bias adjustment on solid state amplifiers
If your amplifier is in for service, the bias is a thing that should be checked by the service technician (and its very likley that the technician will have to check it anyway if the service has anything to do with a damaged output section). Its n... 
AYRE VX-5 TWENTY- WHICH TUBE PREAMP MATCHS
In order to really get all you can out of the amp you do need a balanced preamp as you've already surmised. But what most people don't realize is that there is a balanced standard; and that this standard is there to prevent ground loops and also p... 
Is there an affordable long run XLR preamp to amp cable out there?
Atma-Sphere and BAT opinions are of little value unless you use their equipment.That is not entirely true. Some high end cable manufacturers obtain Mogami wire and re-brand it. The wire is oxygen free and the dielectrics are polyethylene; pretty n... 
Help me rebirth my old turntable
i don’t understand why it doesn’t sound better unless it is not set up correctly or the needle is worn out.  I probably will need someone with more expertise in turntable setup to take a look at this and give me an idea of what my next step sho... 
Cartridge Impedance
The loading is strictly for the preamp’s benefit and does nothing for the cartridge.The reason it is there is because the inductance of the cartridge and the capacitance of the tone arm cable form a resonant circuit known as a tank circuit, which ... 
Help me rebirth my old turntable
I should have googled it! Dual made some very interesting direct drive machines. Their motors were quite nice.  
Does anyone have experience with Bohlender Grabener RD 75 ribbon transducers?
BG isn't in business anymore and the drivers have failure problems associated with tears in the diaphragm. If you have a set that works people are looking for them to replaced failed units.

As a Vietnam vet and infantryman the only thing M-60 means is the U.S . Army’s deadly machine-gun .If this was done for a laugh, it ain’t funny.The M-60 evolved out of the M-50 monoblock amplifier we introduced in 1991. We found that by installing...
