Rated 5 out of 5 by from Replacement for unit purchased in 1969 I purchased a Harman Kardon amp in early 1969. It lost a channel in late 2016, which prompted this purchase. Excellent unit then and now.

Will this support a USB turntable?

Asked by: Lenard
Unfortunately, the HK 3700 does not have&nbsp;phono&nbsp;inputs needed to connect turntables directly, that is why the audio is not amplified. Unless your unit has a built-in pre-amp, you need to purchase an external&nbsp;phono&nbsp;pre-amp in order for your turntable to work with the HK 3700.

I have a Vintage HK 670 from the late 70s, I believe it was the last analog receiver/amp you made. Dig it to the max, but it sounds like 1 channel is no longer working. Is this something that can be repaired or should I opt out and purchase a new receiver

I have a hk880 Vxi stereo receiver with a HD7500 CD player with Klipsch R-15M speakers. Can I replace the hk880 Vxi with the hk3700? The balance knob no longer works and only sends sound to one speaker.

Why does the HK3700 switch off after 8 hours even though it's playing music? It's very annoying having it stop right in the middle of a song. Is there any way to configure it to not do this?

I have a TEAC A-2300SX will this HK3700 work with my real to real?

Asked by: Leo 1
Unfortunately it would not, The Receiver must have a Tape Loop (in and out) or a Pre Out/Main In section. This receiver has neither. The last receiver we made that had this capability was the HK3490, and that has been discontinued for quite a few years.

I am interested in the HK 3700, but I need to know if I can hook up my graphic equalizer to this amp and how that would be done without the old tape monitor connections that we used to use.

Asked by: Frederick
The HK3700 does not have the &quot;main in&quot; and &quot;preamp output&quot; connections required for an equalizer. The HK 3700 has tone controls where you can adjust the treble and bass. This eliminates the need for most equalizers.
