You and Jason must be good friends.

You do a great job of promoting his gear and it looks like you must have bought your entire system from him.

So Tom; are you Jason, or are you working for him, or have you merely spent close to $80,000.00 on his kit?

Hi Halo88

A quick post before I go & support the Hurricanes play at 7.35 pm tonight.

Marantz T1 Project mono blocks have to be in the top 5 amplifiers I have heard, thanks for the link.

 

Ernie, I have a few ice cold Guinness left over so I will have to join you in a stronger brew....or 2.

 

Have a great week end guys & look out for the release of the new Fat Freddy`s Drop album very soon now.....

 

Cheers Tom.

Is this so unbelievable that he must be Jason or work for him? :rolleyes:

 

If I had 80k I might spend it all with Jason - he has nice gear. Doesn't make me Jason or an employee though.

 

:rolleyes::rolleyes:

Yup Halo,

Those T1s are double :cool: :cool:

 

Apart from using 300Bs to drive the big 845s, they are fully symmetrical Push Pull(not SE), transformer-coupled from input to output... that's 4 x audio (interstage & output) transformers inside those svelte boxes.

 

And.... they use 2 addit. 845 tubes as rectifiers in the PSU in order to generate the 1000vdc for the output stage 845s!

 

So lemme see, thats 4 x 300B triodes, plus 4 x 845 transmitting triodes, plus 1 x 5U4G rectifier... phew!

 

I think ea monoblock weighs 65kgs.

Thanks Owen & Tom. :)

Beautiful amps, a cost no object design & obviously now out of production.

I do remember Marantz amps like these at Sound Line here in Christchurch some years ago.

Any thoughts on the cost when new??

Tom what happened to these pair?

 

Regards. :)

The last I read (2003), the T1 was avail only in Japan.

 

Introduced in 1995.

Actually I recall Mike Wildash, formerly the distributor of Marantz has Marantz valve amps in his collection. Even earlier models than the ones described in this thread. I do believe they were one of the first manufacturers who enabled their amps with the ability to change from single ended Triode to Ultralineare mode at the flick of a switch. This is now a reasonably common feature amongst some more recent valve amps.

 

Mike would be the Marantz specialist to talk to...

Ernie is right, madam (as Harry Enfield would say :D)...

 

There was a Marantz 9 Replica release of that legendary tube amp from the early 60s.

See... http://audio-database.com/MARANTZ/amp/model9replica-e.html

 

(Sidebar: The Triode/Ultralinear switching options on some amps, relate to Push Pull amps with Pentode/Tetrode tubes, switching betw quasi-triode & tetrode/pentode. SE Triode tis another animal altogether.... to the best of my limited knowledge ;))

Hey team

 

Can't look at TardMe just now as am stuck at work (working hard, as you can tell) but will be interested to peruse when I get home tonight.

 

I did listen to a pair of Marantz Project T-1 amps at the Listening Post in Hamilton back in 2002. I had just finished sitting my big ugly specialist exams and so may not have been at my critical peak, but I can say they were FANTASTIC, and had my Lotto numbers come up that week they would have been integrated into a system involving a Wadia CDP and a pair of Sonus Faber Amati Homage speakers. Warm yet detailed, with authoritative bass (partnered with Wadia CDP and BIG Proac speakers). The glow was gorgeous too :cool:

 

At the time they were for sale 2nd hand (had been in someone's holiday home and apparently he felt they just weren't getting used enough?!?!) and were priced at NZ$65,000 the pair. Sadly the Lotto numbers did not come up that week (nor have they since...) :(

 

Rumour had it they eventually got sold (don't know at what price) and went off-shore (can't remember where exactly), however maybe that's all just urban myth and this is actually they.

 

Guess I'd better get down the Lotto shop then... ;)

The Marantz T1 Project background on this pair which is no longer in the country, sorry.

This was the only pair that came in to NZ ($50,000 USD new), they were owned by a wealthy local Audiophile who asked a few local Audio dealers to help sell the amplifiers for him, that is why if your were one of the lucky few you would have seen & heard them in a few local audio dealers around the country.

They were sold to Parmenter Sound who owned them for 6 months before the Marantz T1 mono blocks were sold to a off shore high end Audio collector friend of Jason`s.

The amplifiers were incredible sounding on a wide range of speakers with 50 watts transformer coupled Class A triode output power.

65 Kg each mono block in weight, the T1 projects were made from 1995 to 2001 as their flagship product from Marantz as a swan-song credit to their head designers career.

Thanks Tom.

To Tom,

 

Thanks for the detail story...

Yup, Halo, that's the one...

 

Note the beautiful symmetry of the (top part of the) circuit... it is a Push-Pull cct, but unlike modern PP ccts that have a non-symmetrical tube phase-splitter, this one uses a interstage phase-splitting xfmr - standard approach back in the vintage old days.

 

2nd thing to note is the use of 300B power triodes to drive the 845 output triodes. And again, the input tubes are 300Bs, interstage xfmr coupled also.

 

Note also that the input is also xfmr-coupled & as the design is fully balanced throughout, accepts balanced XLR input.

 

The whole thing produces 50wpc.

 

The PSU (bott part of schematic) is unusual in that it uses another 2 x 845 power triodes as rectification, to produce the super high voltage (980vdc) for the output triodes.

 

So, you can see that this is a pretty all-out effort.

 

One other thing, I read somewhere that the audio transformers are USA-made, not Japanese... interesting.

 

Definitely :cool: :cool:

Hi Owen

The Marantz Project T-1 uses transformers manufactured by OPT of America formerly UTC: United Transformer Corporation.

Thanks Tom.

Hi Beeman,

That's what auto bids are all about. ;)
