I am selling my Triode TRV CD4SE CD player. This unit has a vacuum output stage. This player is built like a tank and in great shape and looks very cool to boot. Includes the heavy metal remote . Even has a mute control and can also shut off the display Details on the design below. The player does not have lot of hours on it and operates smoothly as it should with one NOTE. While the laser is strong as it tracks some of my really scratched discs others will not it has a quirk. If it sits for a while of sometimes on start up the laser will skip for a few seconds. If one pushes a different track or hits stop and starts over .It straightens out pretty quickly and performs as it should from there forward with no issues. . Usually in under 30 seconds. Odd. The sound is slightly warm and natural. with very good detail but not clinical. Went for over $2200 new and not that long ago. I am asking $549 which is a steal Thanks
In the player we have metal buttons and a blue display hidden behind a mirror window. It is not big but quite bright. Next to the display there is a bright blue LED that is lit when play is pressed. According to the user manual the LED indicates upsampling – the device changes the 16/44.1 words to 24/192 before entering the converter. The display can be dimmed in two steps, but it cannot be turned off. We have also quite a lot happening on the back panel. We have digital outputs, RCA and TOSLINK, and two analog outputs – unbalanced RCA and balanced XLR. There is also an IEC mains socket. The device is places on nice aluminum and rubber feet, the same feet we can find in CEC devices. Inside the player looks equally nice.
First the drive. This is a Sony unit with the KSS-213 pickup, exactly the same model that was used on the Ayon CD-1 player, albeit without the tray elements. The drive is screwed tight to a very rigid and heavy plate, where, in a cut-out the servo PCB is placed. The main microcontroller is placed on the separate, main PCB to the side. This PCB covers the half of the insides. The signal from the drive goes to the large Philips SAA7824 IC, that decodes the data stream and acts like a digital servo. Later the signal goes to the D/A converter Burr-Brown PCM1792. This is a delta/sigma 24/192 converter with integrated upsampler, active in this configuration. Behind the converter we have a nice analog section, almost fully balanced. In the I/U conversion and in filters popular NE5532 chips were used, and in the amplifying section the LME49710. All ICs are placed on sockets. I mentioned that until now, all the circuitry is balanced. So I do not really understand, why the output buffer is made using only one single tube (the double triode 6922EH Electro Harmonix) meaning that it is unbalanced. The tube circuit is based on very good passive elements, eg. very nice capacitors Mundorf RealCap, and the output is coupled by very large WIMA capacitors shunted with the same Mudorfs.
I concentrated on the audio circuits while ¾ of the interior is filled with power supply circuitry. Just behind the IEC socket there is a significantly sized PI filter, followed by a medium sized toroidal transformer. It has many secondary windings. The left and right channel in the solid state section are powered separately, there is a separate power supply for the anode voltage and heating. Also the drive has a separate power supply – at least it seems so. It looks very solid, the constructors remembered about shunting the rectifying diodes with capacitors in the power supplies. The top cover is very thick, what reinforces the chassis additionally. The metal remote is not very comfortable but it is solid.

Oh man... that would sure look nice on the third shelf down (pardon the dust). I’m gonna have to really think on this one...

If I played insted of ripped CD's this one would do the trick. She's a beauty brother. GLWS and hope it stays in the Polk Hood!"if it's not fun, it's not worth it & remember folks, "It's All About The Music"!!

Received the Triode today. Projects are delaying my hooking it up and giving it a listen, but I did have a few minutes to unpack and have a look. This is truly a work of art and the build quality far exceeded my expectations. The cover paint is automotive quality. The inside is spotless and very nicely laid out and organized. An unexpected bonus - looks like the tube had been upgraded to an Amperex Bugle Boy.
Keith is an awesome seller. He took the time to talk to me about the minor issue before the sale. Very well packed and great communication throughout!
Here are some pics:

Thanks for the guts photos!
