AmpRx BrownBox Voltage Optimizer for Vintage Tube Amps.1st ISSUE Hardwired 1 INP

Description

AmpRx BrownBox Voltage Optimizer for Vintage Tube Amps..
First issue hardwired Brown box with one input outlet and hardwired AC CORD.
This has been used a handful of times.
I had bought 4 at the time and this is an extra one.
This really is a must to have with your vintage amp!
We must always take into consideration that when these vintage amplifiers were made in the 1960s and early 70s the voltage was completely different coming out of the wall! The power aka voltage was much lower and that effects the tone!
This box allows you to lower the voltage to what it used to be to get your amps to sound the way they should
This is the first issue brown box with one outlet, circuit breaker and a hardwired AC adapter.
Some people like this hardwired version better.
You no longer can purchase this style so it does have a collectors value more than the other brown boxes that are for sale today.
These were the ones that were made in the beginning when they really had to prove something.
