Time for another oooolllldddd skooool Amp Dyno test!

This time we try out one of my dream amps from the early/mid 90's...the Phoenix Gold MS-2125. No, this is not a mega-thousand watt Chinese made amp...this is an SQ amp, made here in the USA and has one of the most beautiful guts of any amplifier out there. 24ct gold plated 2 sided circuit board, solid copper (along with 24ct gold plating) buss bars, etc. No built in crossover, just pure, raw, clean power. Trust me, this amp sounds as good as it looks!

The MS-2125 was available from approx. 1992-1996 at a cost of $820 USD.

Let's see how this beauty performed on the Amp Dyno...

halfway through the video right now...and man, just the build quality of this amp is stunning. It's what made me fall in love with car audio back in the day. Amps that i wanted but could not have...like this one.

thanks for the test! Ima finish the vid now :popcorn2:

I had one in my ranger. Reverse mounted with the plexi back plate that had all of the components labeled. 2 punch 12" connected to it. Loved it!

Current system:

1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s

Previous systems:

2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz.

1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.

Greetings from Germany,

first I thank Steve and BigDWiz  for the fine videos. Love old skool gear!!!

And now I show you how to form the caps and guts of the MS-2125 2-channel Amp that was played last time over 10 years ago. So conditioning of the caps is needed to turn it on. Some germans do not use resistors...

So here you see the famous Frank-Amp 'N-Stein. Only 100 of these legendary amps were even made — and they actually contained two separate amps, pairing an MQ-430 4-channel amp with an MS-2125 2-channel model.

Running with 12" in front of it - like to play it slo_w;)

Ahh 018! Those are mili Amps;)

A very low current is needed to form the selected Caps inside the Frank. So you fill the Amp soft. This takes hours. I stopped and 4.5 V and charged my camera LiPo to give the parts time to condition and the caps like that too. The term forming the cap is used for high end tube amps, so why not use it for audiophile car amps;)

Now the surprise. At 7.9 V the amp was on after over 10 years of sleep. So I lowered the voltage to see were it will turn off. At about 7.5 V the Amp turns off!!!

That is why it was called Frank-Amp 'N-Stein? It runs deep into the Voltage drop and delivers... Audiophile car amp history

Note: No playing at this stage. Rise the Voltage slowly to wake up the Frank-Amp 'N-Stein in your Amp...

No need to built in crossovers if you have those:

MQ-430 4-channel amp and the "chinesium" PG 300 W 4-channel amp I run to chill the Frank Amp 'N Stein - you can hear differences and when i played a 2 Ohm JL audio woofer the "chinesium" PG 300 W 4-channel amp had no chance!
