[R-390] SSB adapter

Mon Aug 15 21:19:08 EDT 2011

I work in engineering for a TV station.
We use a number of Wohler audio amplifiers for monitoring.
These are typically 1 RU in height and require 24 V either AC or DC to operate.
The inputs can be XLR/RCA/Phoenix.
These amplifiers are high fidelity and magnetically shielded.
There are a number of these on EBay now in the $100.00 range.
There is at least one group of 2 for $100.00.
The amplifiers that we use are AMP-1A and their variants.
I personally own a 12 channel AMP-1A that I bought on EBay.
These amplifiers can be loud.
The only controls are volume, balance and channel if multi channel.
These, for me, make a good amplifier for our line level boat anchors 
as the input is line level.
If you do buy one, make sure that the one that you get is for analog audio.
Wohler makes analog, AES and SDI audio amplifiers.
