FS only: Demeter 300W Valve Amp

Post by basshack » 18 Sep 2018, 08:03

As flagged in another post, and because it's getting a bit of attention from that post, here is details on the Demeter Amp for anyone else interested.

From the Demeter website

Designed for heavy duty use, the VTHF-300M is equally at home in the studio or on the road. Its all tube high fidelity design rivals and surpasses the sound quality of many of the so-called audiophile amplifiers, yet sells for substantially less. Its awesome power (300 W RMS pentode/150 W triode) can run any speaker through its paces with the accuracy, definition and fullness that only tube amplifiers can deliver. Featuring a custom designed and high current bifiler audio output transformer, regulated B+ to the preamplifier section, individual output tube bias for long tube life, pentode/triode switch, variable feedback control, heavy duty binding posts, gold plated RCA input connector (1/4 phono and Jensen balanced 3-pin also available), optional two speed fan, toroidal power transformer, solid power supply (880 mf @ 800 volts), Demeter selected tubes, a beautiful heavy duty aluminum and steel chassis, all hand built construction in the U.S.A. using only the best quality components.

Specifications
Output power: 300 watts RMS pentode / 150 watts RMS triode
Output impedance: 4 and 8ohms
Nominal input impedance: 100kohms
THD: Less than 0.05 @ 1 watt
Bandwidth: 20 to 20 kHz - .7dB
Preamp tubes: 1 - 12AX7a, 1 - 12AT7a
Power tubes: 8 - Svetlana 6550c
Mounting: 4 space standard rack
Operating voltage: 240/120V AC
Dimensions: 7" x 19" x 12"


I have it racked in a Gator 8 space rack at present but I also have a heavy duty 4 space enclosure I can put it in to if your interested. This one has the fan option installed and the 1/4 phono input with binding posts for the output. I have a fly lead to speakon male I made up for it. I was going to put a speakon into it but never got around to it since it doesn't go anywhere.

Pictures to come later today but it looks like the one on the Demeter website. There is a cover over the bias adjustment screws the picture doesn't show.

Located a bit north of Melbourne and I'm looking for something between $1,500 and $2,000. I can pack it for transport at your expense but it is heavy. They don't say and I haven't weighed it but it has to be ~30kg.

Ooooh err.... this is my dream all tube power amp. I canna lift it at that weight and it's too nice to stay home, so I don't really have a use for it unfortunately. Would sound killer with the hellborg pre on ebay right now.
