Hobbyauflösung wegen Umzug Leider wurde nicht bezahlt, deswegen wird nochmal angeboten. Der Verstärker ist mein DIY Projekt basierend auf Nelson Pass F5 Turbo Verstärker Die Platinen und die matched Teile waren direkt in USA bei DIY Audio Shop bestellt . Das Gehäuse ist von ModuShop(Italien). Restlichen Komponenten habe ich hauptsächlich bei Mouser Electronic gekauft (somit originale hochqaulitative Komponente). Beshcaffungskosten waren hiermit bei ca. 900EUR ohne Kleinteile. Der Netztrafo ist ein 800VA Ringtrafo von TOROIDY.PL mit 2x24V Der Vertärker ist vollfunktionsfähig. Ich bin mit dem Klang sehr zufrieden, muss ihn LEIDER verkaufen, da ich wegen Umzug mein Hobby komplett auflösen muss. Ich habe den Verstärker sehr sorgfältig nach der Bauanleitung gebaut, allerdings handelt es hier um ein DIY Verstärker, der ausschließlich als Bastelgerät verkauft wird (wegen Stromnetztanschluß nicht geeignet für unerfahrene oder unqulifizierte Person) Der Verstärker wiegt ca. 22 KG. Ich werde dann mit 31KG Packet verschicken und habe somit noch die Möglichket die Verpackung gut zu polstern. Bei Fragen einfach mailen. S.

Nelson Pass designed amplifier. The PA-5 (and PA-7) use Passs Stasis technology. Nakamichi overstepped the license and used ALL of the topography. They got sued, hence, the PA-5II & PA-7II. The original series sound much better, they are amazing sounding amps. They are 100% Pass design! This amp, while not perfect, is quite clean, and functions perfectly. A lot of music for the money. They run warm. These are know for clarity and a sweet sound. Power output: 100 watts per channel into 8? (stereo) They are known to push out as much as 140W before clipping.

Excellent example of a legendary power amplifier. Nelson Pass design, and in this iteration it is improved with MOSFET circuitry, which has a bit richer, warmer sound. A bit tubelike. Gobs of power, 200 watts x2, will drive anything with authority. Absolutely excellent condition, very clean on the outside (see photos). Inside in great shape as well, just a bit dusty, see photos. Recently checked out and given a clean bill of health. Sound is just wonderful. I would keep it but it’s massive and I don’t need 200 watts. I purchased this from the original owner, and it was obviously well cared for in his home listening room. It comes in the factory box with the owners manual. An excellent amplifier in all regards. I’ve done my best to describe the condition, and provided plenty of photos. If you have any questions please ask. This amp weighs 48 pounds and will be expensive to ship.

This is my own personal amplifier. It has been used sparingly and babied. There are no scratches that I can see. It is a beast and will power any speakers you have with headroom to spare. It is in excellent working and cosmetic condition. I sell and ship drums for a living so it will be packaged with extreme care. The reason for selling is because I am moving and taking next to nothing with us. The ESS speakers you see are what this Amp was powering and that are also for sale. THERE WILL BE NO RETURNS OR REFUNDS

Legendary Nelson Pass designed Mosfet preamplifier. Desirable blueboard model Original paperwork Original box and packing(see picture of original box for condition) Gfp-rc Remote This will be reboxed with protection for shipping You would be hard pressed to find a finer example of this piece. Im simply moving on to a unit with integrated phono and I dont have space for another seperate. Shipping on following Saturday after purchase Lower 48 only As with all vintage audio and musical equipment, sold as is

EDIT: I received a few questions regarding this pre: Blue Boards: I had completely forgotten about the blue board thing. I never took pics through the top vents and I dont show any notes in my records to confirm this is the blue board version. However, my original 750 had these and I was aware it was important when I replaced with this unit. So Im 95% certain it has them. Im not up to unwrapping/rewrapping; so, if this is critical to you, and you purchase and find its not blue boards, I will accept return. Jumpers: I do not have the original CD jumper pair. Completely forgot about this as well - I was using balanced XLR on the CD input. So if you want to use all 5 of the unbalanced RCA inputs simultaneously, youll need to purchase 2 jumpers. These are available on eBay for $10/pair here: https://www.ebay.com/itm/402627903791 Thanks for the questions,Craig Cosmetic Description: Good condition with minor scuffs and scratches. The metal switch plate has been polished slightly through the gold plating. I wrote on the back of the remote. See pics. Included: Manual, after-market remote control, generic power cableShipping: FedEx Ground (CONUS only) MSRP: $1250No. of Owners: 2Tobacco Exposure: NoSerial Number: P751DB05774 This is the very well regarded Nelson Pass designed preamp that made Stereophiles coveted Recommended List. The passive mode bypasses everything except the input selector and the very high quality low-noise volume knob. It also includes a Processor loop which can be used as a HT bypass. So: exemplary solid state performance, HT bypass, 3 outputs, remote = the perfect preamp for a combined HT/stereo rig. I bought and used one of these for years in my best den rig which also served HT duties: By connecting my AVR front preouts to the 750’s processor input, I could use my higher end amplifier and speakers in the HT rig and not have the clutter of separate HT speakers AND get much better front L&R sound. I also occasionally used the Processor loop to inject some tube soul with the little Dared SL-2000 preamp. I immediately regretted selling my old GFP-750 and bought this unit which was cosmetically inferior and had an aftermarket remote. It has served me well for several years and I will miss it but due to health issues, must sell all but a couple prized pieces that will go to kids.

This has been a workhorse for me for 20 years. The volume control needs servicing it is making scratching noises when adjusting but once set at a volume it works. So if you are a hands on hobbyist or know a good service tech this could be a great find for you and your classic audio system. Designed by legendary Nelson Pass this was an under the radar audiophile favorite back in the day.

Also for sale on US Audio Mart, potentially for a lower price, so this listing is subject to prior sale. Nelson Pass designed Adcom GFA-5400 stereo MOSFET power amplifier in excellent operating and physical condition. Would be hard to find a nicer example of this amp.Original, unmodified, and clean inside and out. Small scratch on top edge of faceplate as shown in photo #12, not very noticeable. Otherwise near mint.Originally $725, hard to find a better amp today for $325. Will ship for a flat $55 via insured FedEx Ground anywhere in the CONUS.

Adcom GFP-750 - Audiophile Level Nelson Pass Designed Stereo Preamplifier Bought an Ayre K5xe mp, my system has been so upgraded, it has outgrown this overachieving preamplifier. Class A Stereophile magazine rated. Also comes with programmed aftermarket remote. Used it for volume control, not sure what else it will do as volume is all I need. I unplug my gear when not in use. I will insure the preamp when shipped. Checked the pricing at the big used audio websites and $650 is the best price. Audiogon has no 750s and US Audio Mart has one at $650
