Conrad Johnson Premier 12 Monoblocks for Sale

[WGS57]

Thank you for viewing! I live in Nova Scotia, Canada located on the east coast, and I am the current owner of these very fine sounding Premier 12 monoblocks. I am willing to meet up with you part way (depending on distance) and I will consider shipping but that will depend on what I can find for boxing here in Nova Scotia. Shipping could be expensive as they are heavy and I don't have the original boxes.

I have a pair of Conrad Johnson Premier Twelve Vacuum Tube Amplifier Monoblocks, rated at 140 glorious tube watts per channel, that should drive most speakers and are rated a 7-8 out of 10...in good condition. The speaker taps I believe are set for 4 ohms but can be changed internally. The cages are also in good contain as well with no dents or chipping. There a small scratch on the side on one of the units but doesn't affect the aesthetics as you can see in the photos...it never troubled me but I would feel more comfortable saying the condition rating should be set between 7-8 out of 10, because of its age. The right channel mono block has a small scuff on the front panel and a slight nick. If you like I can supply you with more pictures.

These amplifiers were purchased from a private dealer in North Virginia, USA and I don't know the age of these amps but likely originally sold in the 1990's. The serial numbers are consecutive. These amps have been very stable with no issues since I have owned them. These are built to last and they are held in high regard and provide the CJ house sound that owners covet. These amps do not have the C1 Teflon upgrade.

The 5751 tubes and 6FQ7 driver tubes are NOS with about 150 hours, and the 8-6550's have 400-500 hundred hours on them. I also have 8-KT120's that I am currently using and have about 150 hours on these tubes. The 8-KT120's came from Upscale Audio in California and the 8-6550's came with the amp when I purchased them in late summer 2022.

If you buy the monoblocks with the 8-KT120's and 8-6550's the price will be $4,600 USD + shipping cost from Nova Scotia. The price with just the 8-6550 tubes will be $3,700 USD + shipping cost. Shipping to be paid by buyer.

All the reviews are extremely favourable, please see the links below.

THE BELOW IS TAKEN FROM THE CONRAD JOHNSON WEBSITE:

The Premier Twelve is a mono-block tube power amplifier.
It used two pairs of 6550s to produce 140 watts for each mono-block.

The Premier Twelve used only the finest component parts in all stages including the power supply. The power supply used only polypropylene and “cjd” polystyrene capacitors as opposed to the traditional deployment of electrolytics. The main storage reservoir used polypropylene capacitors with polystyrene shunts.

Features:
- One pair of binding posts using the default 4-ohm tap
- One pair of inputs
- Two plate fuses
- Power switch

Cages have been extended using gold coloured speaker feet to accommodate the additional height of the KT120's. Easily returned back to their original placement but I think the cages look very cool as they are, and cages are easily removed when you just wish to look at the tubes without cages.
