Sonic Holography - Autocorrelation Preamplifier
This is a very clean example of one of one of Bob Carver's most sought after vintage preamps. The only cosmetic flaws that I can find are some slight scratches on one of the rack handles. It is 100% functional and has no noise in any of the controls.
Take a look at the many photos included below and you'll see that this is in "collector quality" condition.
The original box is gone, but I can pack it well for safe shipping.
