Yup, Crown made a Reference 1 and 2. Both pure class A room heaters.
 
But not like a Gates BC5E.

So hot I found no trace of one on the internet after nearly 50 years of one in the KSRV House down the road!

OK, thank you again Barry Mishkind at oldradio.com (a king of his genre)

My new toy to go along with the Phase Linear T5200 tuner and a DRS 400 or DRS 900 amplifier that I have not found yet.

I like this one because the OPAMPS are plug-ins. I've already replaced the TL072s with LME 49860 devices. I hope the pinouts are the same!!!!!

Joe,
I finally received the Crown amp. You are right, this thing is a tank. The whole amp is a heatsink and it weighs as much as a 700. I am going to have to study it a little bit. What is up with that big multi-section resistor, they don't like the little ones? I have the fuse cover but there are no fuses, I need to locate some of those.

It looks complete but it is not perfect, it has been resprayed, one output is not original (Motorola 3990 instead of the 2N3773) and some of the screws are not original. I'll be looking for those.

I'll be in Boston this weekend, wanna go sailing in the harbor? When I get back, I'll test the amp with the DBT and power it up.

Mark

Oh look, I found my USB floppy drive!

I bought a boatload of new floppies for 88 cents each on 88 cent day and now I have to reformat all of them as they are Mac formatted!

This one was disk 6 of Win95![attachment=3:y4stuqpv]Windaz 9fiva.JPG[/attachment:y4stuqpv][attachment=2:y4stuqpv]MVC-005S.JPG[/attachment:y4stuqpv][attachment=1:y4stuqpv]MVC-006S.JPG[/attachment:y4stuqpv][attachment=0:y4stuqpv]MVC-007S.JPG[/attachment:y4stuqpv]

Battery charge!

Just finished listening to Pink Floyd's "One Of These Days" from their Meddle album (1971). I cannot tell you how technical and complex this piece is. The opening consists of an eerie wind sound made by a delayed wind machine played at half speed and dual punishing bass lines that are double tracked from both Roger Waters and David Gilmour. Water's bass is on the left and Gilmour's bass is the weaker muted sound on the right. The story is that Gilmour's bass guitar had old strings on it and the roadie sent to retrieve new bass strings wandered off to see his girlfriend. The contrast in sound from the two bass guitars has never been recreated.

The threat heard at the 3:00 mark is a rare vocalization from Nick Mason played through a ring modulator. He says in a robotic, mechanical voice: "One of these days I'm going to cut you into little pieces" which refers to cutting the tapes of BBC disk jockey Sir Jimmy Young into little pieces because Pink Floyd thought his babbling on the radio made him sound foolish. Otherwise the song is an instrumental with no vocals.

The Hammond keyboard work and special effects of Richard Wright are especially mind-numbing at mach 8 with swirling octave melodies and pulsing low frequency tones that hammer at your brain as your face melts down into a shallow pool of goo around your feet. Just when you think you've had enough, a screaming guitar solo from David Gilmour out of the left speaker assails your inner ear with soaring staccato riffs that scream like bullets flying past your head, while at the same time Gilmour duels with himself via multi-tracking on a slide guitar out of the right speaker that sounds as if 10,000 razor blades are stuck in a Waring blender at top speed and your head is in the blender too.

The Japanese release of this song was titled ????????? (fuke yo kaze, yobe yo arashi?), which loosely translates to "Blow, Wind! Call Forth, Storm!"

Gotta go back and hear it again. I think there was another version on The Delicate Sound Of Thunder. I understand it was also on the LP version of Pulse but not the CD version of Pulse.

I think you will enjoy the C-2a, it is well known for its excellent phono stage and tailorable resistive and capacitive loading for the MC stage which, as you note, it very unusual for a preamp.

It is built like a tank, not like the more consumer grade gear that Yamaha put out. It was units like this that put Yamaha on the map in the audio space in the first place.

Have run into a problem with the C2a that I haven't been able to find a solution for. There are two unique to Yamaha fet amps called 2sk101 that are bad in both channels. Not able to locate these puppies. Any ideas on how to find or how to suitably replace anyone? It's in the equalizing section of the phono circuit.
 
thanks for the links Larry, but I'm pretty sure the Yamaha 2sk101 is a different animal than all of the 2sk1010, 1011, etc. I'll know for sure as soon as I get the unit back in house and can see the part.
 
Let me know Scott, I may have a line on some.
 
Thanks Lee. I haven't picked it up yet, needed some river time this weekend. I'll have it today or tomorrow so I can see the original component and get a pic.
 
Hey Lee - do need help on this one.

Only info. I can find on it is N-channel, dual JFET, Breakdown voltage of 15V, Power D is 100 x 2 mW, 7 pin SIP pkg.
 
Hve you given thought to using 2 discrete JFETs to replace the original SIP package?
