RE: Kinergetics KBA-75
I have a KBA-75 gold (the original one with the big red power button on the front, not the later platinum). Those jacks are the same. They can be used for bi-amping. I use them to feed the KPA-1 output to a tube amp, so it is easier to switch amps... 
Anyone heard the Kinergetics KBA-75 amp??
I agree with Blue Swan. I've had mine since early 2010. Only problem is the big red power switch (this is the original KBA-75 which I refer to as the gold one since the second model of the KBA-75 is called the platinum.) The switch is still availa... 
Vintage Kinergetics gear repair by someone that knows what they are doing?
I have not used them, but I have a KPA-1 and a KBA-75 gold that are working. I was looking for info one day and spotted this adhttps://kahlaudio.com/products/kinergetics-kba-75-platinum-series-class-a-amplifier-legendary-2000-m...So I e-mailed him... 
apt holman problems
Also, even on pre-amps that are encased in solid metal on all six sides, do not have a pre-amp too close to a power amp. Even if the power amp is off, some keep the power supply on standby, generating an electromagnetic field that can cause hum. I... 
Apt Holman repairs
Just from searching (since I have the pre-amp and amp), not from experience)https://audioproz.com/AP.php?Article=64https://audioproz.com/AP.php?Article=95https://quirkaudio.com/?page_id=895https://quirkaudio.com/?page_id=952https://quirkaudio.com/... 
best preamp under 500 for cheap, poor student
You may be able to get the Apt pre-amp under 500, but worth it if you pay more. Mitsubishi DA-P20 underappreciated and should fit your budget. 
How do we remember 1970s amplifiers?
Strongly agree Apt Holman pre-amp and matching amp (I have that pre-amp driving two of their amps running as mono-blocks). 
Best Tube Amp under 10K?
Apt Holman tends to refer to the pre-amp. Apt refers to the amp. At least that's what the manual covers indicate. I have the pre-amp driving the amps set to mono-block.  
Sadly missed manufacturers
Also the Mitsubishi - well done, real controls, metal knobs. Items such as DA-P20 pre-amp, A-10 amp, matching meter box. 
Sadly missed manufacturers
Apt Holman pre-amp, and related amp. Kinergetics KPA-1 and KBA-75 
Cheap Old Preamps
Agree on NAD. Have 7020 from 1982 (is 3020 amp plus tuner). Jumper on back to get to pre-amp output. Mitsubishi DA-P20 also. Other favorites are not cheap, such as Kinergetics KPA-1 and Apt Holman. With a small speaker like ADS L420, 7020 sounds g... 
What companies, out of Business, did you LOVE???
My favorite former companies (I hate to say defunct because I'm still running their 30 year old products) : Kinergetics KPA-1 pre-amp and KBA-75 amp. Apt Holman pre-amp and Apt amp. 
Who remembers the Dahlquist DQ-10's?
I have DQ-10s (early model without fuse in back) and DQ-20s. Currently running the DQ-20s with the Apt pre-amp and amp mentioned above. I have two amps as mono-blocks, so 200 Wpc. But sound OK with one amp running both speakers (100 Wpc). I also h... 
Is an Apt preamp a good preamp for my setup.
I have one and am happy with it. Tricky to get cleaner in to pots but works well. Have two companion amps running as mono-blocks. I decided not to plug the mono-blocks in to the pre-amp since would approach limit of switched outlets 
apt holman problems
Manual is at https://www.hifiengine.com/manual_library/apt-corporation.shtmlDoes hum only come when channel cuts out? That sounds like cable.If hum in both channels, the turntable to pre-amp separate ground wire is suspect as others wrote. This gr...
