Anybody have some experience with Bedini amps?

This this is a fantastic forum I to own a 25/25 with oblesk sand I use the model 66 mkII preamp and it is a fantastic combination it is like painting you can see the picture that the artist (engineers) put forward in there work to give a beauty of sound. I’m so much in love with my system it brings joy to my heart thanks to John Bedini for what you gave to audio. 

I have a Bedini 25/25 that I love powering a pair of Obelisks to the level where I once thought I would blow the woofer drivers — the sound was that enormous. I couldn’t believe the sound coming from what are really rather small speakers. Vasken Shahenian assured me I could not damage the Obelisks with the 25/25 since the speakers were rated to 400 watts capable. Glad I found this group - I have a MAJOR ASK - my 25/25 has been repaired 2x here in Las Vegas, where I live, and has lost its magical bass transparency and speed (now sounds thick and muddy at the low end). The tech said it was fixed to full frequency spec on his test gear, but I can tell you it does not have that holographic musicality. CAN ANYONE HERE direct me to someone who knew John Bedini and knows how to restore a Bedini 25/25 as if John were doing the work? I was emailing John prior to Gary passing, and John passed soon after Gary. Broke my heart. I keep my 25/25 not only because it is great but because I have known John and Gary Bedini personally since the 1980’s-90’s. So if I can restore the 25/25, I would be delighted and feel I honored John in the repair. Currently, it is less than, what we are all recognizing as, the Bedini Magic of the 25/25 (which Gary once told me was their most musical amplifier).

@stereotwo  I agree about the Bedini Shaenian system,. Pure JOY.

 

Hello, I know this is a old thread but I wanted to ask if anyone would have any info on the Bedini 66 Mkll preamp? Like age and any other info? I pick one that sat in a hi fi shop for twenty years. It had a hum but I replaced the PS caps and it good to go! BUT if I turn the two balance knobs all the way up with the volume I hear his and slight hum. Is this preamp worth using? Its clean sounding except the hiss. So not the Darkest background but can really tell at what playing music at normal volumes. I guess it runs in pure class a because of know power switch. the highs are tad vintage sounding if you know what mean?

Thank you!

Only analog

@onlyanalog The 66 pre-amp was released alongside the MkII amplifiers I believe. There was also a 6677 pre-amp that was dual mono (it was just two 66 pre-amps stacked on top of each other with one face plate.

 

I read somewhere that the pre-amp pairs well with the Bedini amps because they both invert polarity, but I can't find where I read that right now.

 

Here's the specs for the 66 pre-amp from the manual:

RMS Power (@ 1kHz): 11.5 Volts into 600 ohms

Freq Response @ Full Power: 5Hz to 35kHz

Freq Response @ 1 Volt, 600 ohms: 5Hz to 100kHz

Phono Overload: 1Khz, 500mV

Phono amp output Voltage: .5 Volt input for 6.25 volt output

Slew rate in Aux: 100 V/us at 11.5 Volts output

T.M.I. - .22 20 Hz to 20 kHz

T.H.D. - .015% 20 Hz to 20kHz

IM Mixed Frequency 4:1 ratio - .015% 20 Hz to 20kHz
