2006 Fargen Mini-Plex MKI 12W Combo Tube Amp

Well...after having this for two weeks I caved and purchased it from my friends wife - Fargen Mini-Plex MKI 12W Combo Tube Amp (Original Version). It just sounds too good plus I love the Decades Switch (JTM, Plexi, JCM); particularly so on 80s plugged into the High Input.

I don't think most people have a clue what this amp is or who Fargen is. Until you've played one; you've no idea of how truly wonderful and unique an item it is. I have been in possession of the the Fargen for a couple weeks now and have had the opportunity to research it a bit as well as plug in and play it. It is indeed a very unique little amp for sure and as described by Fargen - a perfect home practice or recording amp for a tasteful tone connoisseur. I can certainly appreciate the loyalty and love that I read from Fargen Owners in researching this little soulful beauty. It's a sweet little amp.

Like many boutique builders, Ben Fargen (pronounced Far-gen, as in Gen-X) does everything himself. There's no greater motivation for quality than having your name on the front, and there's also no payroll leaner than a one-man show.

Fargen also simplifies production by using the same basic zinc-plated steel chassis for many of its models, including the Mini Plex. This sturdy and simple open-box design has no extra reinforcement folds, fancy welded corners, mounting ears, or blocks, but it's punched to accommodate every component needed for all the applicable models.

This universal-chassis approach saves Fargen (and you) money because it allows him to place orders for larger quantities, which further amortizes the sheet-metal shop's setup fees. While a good chassis can be costly, an amp's transformers are typically its most expensive components.

The Mini Plex uses a standard Hammond power transformer, and this transformer is used in some other Fargen models, as well. Buying off-the-shelf power transformers in large quantities helps to reduce cost, which allows Fargen to splurge on the Mini Plex's most tone-crucial component--it's custom-wound, interleaved and paper-layered output transformer.


Fargen Cool

From the outside, the Mini Plex may look like just another run-of-the-mill Marshall plexi repro (albeit an upside-down one), but a careful study of its circuitry reveals that it's far from being just another copycat.

For starters, the Mini Plex has a very unusual parallel single-ended output stage. While most amps with two output tubes configure them in a push/pull arrangement, the Mini Plex has two cathode-biased EL34s wired in parallel. You don't get as much power this way, but the tone is noticeably richer in lower harmonics.

The Mini Plex also has a Hi/Low power switch that reduces the amp's output from 12 to 8 watts by disabling one of the EL34s. The Mini Plex has only two preamp tubes.

Of course, a simple design reduces parts count and, therefore, cost, and it also reduces labor time as there are less components to install and wire. And many tone gurus will also agree that a simple circuit can often provide a richer tone, as well.

The two halves of the Mini Plex's first 12AX7EH preamp tube are wired in parallel--a configuration that's somewhat reminiscent of a vintage Marshall preamp with it inputs jumpered.

Fargen's front-panel Decade switch provides three different preamp voicings by bypassing the first stage's shared cathode resistor with a .68uF capacitor for the '60s position (for enhanced upper mids and treble), and a 25uF cap for the '80s setting (for full-range boost). The '70s position leaves the resistor unbypassed for lower gain and more clean headroom. The Mini Plex's Volume knob follows this first stage, which feeds the Marshall-style second gain stage--a cathode follower-driven classic 3-knob tone stack. Immediately following the tone controls, the Master Volume control is a simple voltage divider that also feeds the output tubes. That's right--there is no phase inverter tube like you would expect to see in a typical Marshall clone.

Remember the Mini Plex has a single-ended output stage, so there's no need for a phase inverter/splitter, and the preamp's two gain stages are more than sufficient to drive the EL34s to maximum power. How's that for tube-savvy economics?


Flex The Plex

So how does a Marshall-inspired preamp sound when it's driving a parallel single-ended EL34 output stage? The Mini Plex can sound amazingly lush, rich, and warm at low volumes, and it gets gradually more aggressive and grinding as it gracefully makes the transition into overdrive. Set to Hi power mode, and at relatively moderate volume levels through the J Design Old Dog 12-12 test cab, I coaxed some absolutely luscious jazz tones from a Guild archtop. Grab a Les Paul, crank it a little more, and you'll be steppin' out with some authentic-sounding Beano-era Clapton snarl. The Mini Plex maintains its vintage-amp character and responsive dynamic feel when run wide open, but with only two preamp gain stages, you can't expect modern high-gain preamp saturation. This is truly an amp for those who love classic tones, but want to get them at more manageable, and tolerable, volume levels.

I wanted to buy that from you so bad. It's like the ultimate small Marshall amp.
Enjoy!
 
Re: 2006 Fargen Mini-Plex MKI 12W Combo Tube Amp

Thanks. I have had it and a Mesa/Boogie for about two weeks and plugged into the Mesa twice but I've played around with the Fargen quite a bit...enlighten that it impressed me enough to buy it anyway. Have it serious consideration and ran my USACG Iceman and Ibanez ICT700 (both SD humbucker equipped with DiMarzio 500K Push:Pull Vol/Fender TBX Tones) through it on Thursday and Friday for a hour and a half each note and I was hooked after that.

fargen makes great amp. a buddy of mine has a mini plex and loves it. i havent tried it yet but he raves about it
 
Re: 2006 Fargen Mini-Plex MKI 12W Combo Tube Amp

Yeah; my friend had been pretty excited about it when he picked it up a few years back. Now I understand why he liked it so much.
 
Re: 2006 Fargen Mini-Plex MKI 12W Combo Tube Amp

So you ended up buying it?

If so,way to keep it close!

'Grats!
& may it continue to inspire...
 
Re: 2006 Fargen Mini-Plex MKI 12W Combo Tube Amp

Thank! Yes I did buy it. After playing it enough to get a feel for it and then dialing it in on a couple of my guitars I was really impressed by its tone in all three Decades. It has a very "pure" tone for lack of a better word to describe it at the moment and it does a nice clean to 80s Rock sound, it's portable and in mint condition, etc...I simply found myself really liking playing through it.
 
Re: 2006 Fargen Mini-Plex MKI 12W Combo Tube Amp

Thanks! I'd never have seen a Fargen if it weren't for this one. I tried it and the Mesa/Boogie DC-2 and they're totally different animals. Having a 5150 60W 2x12 Combo already the DC-2, although a nice amp in it's own right, just didn't "stand out" tonally to me like the Fargen.
 
Re: 2006 Fargen Mini-Plex MKI 12W Combo Tube Amp

Very nice! I've nothing but good things regarding Fargen.

The 68 Lead & Bass Plexi head is on a short list right now.
 
Re: 2006 Fargen Mini-Plex MKI 12W Combo Tube Amp

Very classy looking amp and I'm glad you've kept it for yourself. I'm sure your buddy would be thrilled and so will his wife, may it continue to inspire you AND remember good times with your mate. Well done sir!
 
Re: 2006 Fargen Mini-Plex MKI 12W Combo Tube Amp

A friend had one of the old Marshall Studio 15s BITD.Pretty cool for what it was,admittedly,but I'd bet the Fargen would eat it alive,esp w/teh "Decade" switch,too cool!!!

'Grats Again,although ...

Fargen A!! (sorry, had to! ) Always heard great things about Fargens.. But this one really intrigues me with the decade switch.. I can imagine the diff tween the decades based on music styles over those decades.. How does the 80s setting differ? and how spot on is it? just wondering as the tube config is limited.. Fascinates me how amps with only one or 2 tubes can sound like something that normally has more

80s has a "full range boost" so it's louder and more dynamic. All three decades offer a familiar Marshall sound. I'm still playing around with it and I've been playing my two Iceman guitars through it. The Ibanez ICT700 Neck-Thru either the "None More Black" Dual Adjustable Pole Piece Jazz/JB TB sounds incredible and brings this amp to full bloom. It's really a great pairing. The Maple Board Bolt Neck USACG Iceman, although it sports a Jazz/CC-JB Hybrid A2 TB is considerably brighter and requires my adjusting the T/M/B Knobs.
