HHB Radius 10 4 channel tube preamp. (USED)

The HHB Radius 10 four channel vacuum tube microphone preamp has controls on all channels include input gain, output gain, +48V (phantom), 90Hz bass roll-off, and phase reverse.  DRIVE and PEAK LEDs show level on each channel. The labeled gain range is 15-75db. Power switch is on the front, also.  Channel outputs are XLR (+4db balanced) and 1/4″ (-10db unbalanced).
Discontinued piece sold under the HHB brand by TL Audio for the North American market. These units were the same as the original Ivory 5001 from TL Audio – see the picture of the insides where it says TL AUDIO on the circuit board.

Having four tube preamps at this price is really a bargain.  Less than $100.00 per tube channel!  I categorized it as good.  It has been in and out of racks a few times in the studio, but, it sounds excellent.  It does have a couple of scratchy Input Gain Pots and of course the notable scratches on the front and top.
