Very nice. What do you like about these versus the stock ones? Thanks
Hi Dr K,
Please tell us some more of the special parts etc inside these awesome looking amps.
P.S I also have a pair of the ALS speakers .
Oops, sorry missed your question. The output transformers are specially designed by Bob and is different than the transformer in his standard Silver Seven amp. It has silver wire secondary windings, and the windings are slightly different as well. The tube sockets are virgin Teflon with Tellurium copper pins which are plated in silver and gold (no brass like almost all other highend pins). The grid resistors are NOS Shinkoh. The plate and screen resistors are custom wire wound resistors with temperature coefficient (TCR) similar to the best nude foil vishay resistors. The resistors in the signal path in the front end of the amp are nude Vishay foil resistors. The output coupling caps are hybrid silver/copper Duelund CAST caps. The signal path wire is gold/silver alloy. The choke loaded power supply contain polypropylene film caps, not electrolytic like almost every other highend amp. It has separate direct input and volume control input with stepped resistor attenuator. The RCA inputs are almost pure copper. The binding posts are the top of the line solderless, Rhodium plated, pure copper pin, carbon fiber housed Furutech posts. Well, this is just off the top of my head. The isolation on this amp alone is around 6 grand (not even retail). Paint job is another 5 grand. There's other stuff I'm missing.
I hired Bob to design a custom circuit for this amp different from his Silver Seven amp. It took the veteran amp designer Bob Carver 6 months to fine tune this amp. I'm thinking about bringing this amp to market, but the final pricing would be extraordinarily high in the six figures.
Hi dr k,
WOW!!!!!!!!!!
That is an amazing list of top of the line components ,you did not cut any corners with this project.
I have been away from valve power amps for a few years and vinyl ( due to Earthquake damage and the subsequent insurance battles) but this amp in this implementation has created a strong desire to revisit valves.
I have been running my Carver ALS with various ss amps Plinius SA250MK4 ,Ampzilla 2000 mono bloc , 4 xSachem mono bloc amps ,Sachem Pure V2 pre amp, Ambrosia preamp ,Lewitt FireFly deluxe valve pre with a Linn KDS Klimax Katalyst streamer as source SR power cables interconnects and speaker cable and power conditioner mostly Galileo level .I found the speakers took a long time ,hundreds of hours to loosen up and change they did and I am happy with them ,as the next level up is as you know many times the price of the ALS .
I have 2x sub rosa subs and used both in my last room but i only have one in operation in my new room at present ,I still have more work to do.
Thank you for sharing your journey with the speakers and amps you have a great looking room that I'm sure sounds fantastic.
Cheers
Russ
That amp is what’s contributing to global warming....yikes. With twenty KT 150’s per side, I should think that one could heat up your mansion in no time...no need for central heating, lol.
Too crazy!
Yes 2 x pair bi-amp!!!!!!!!!!!!!!!!Is there a version with more tubes?
I would consider that amount of heat negligible in dr k's room ,I have the Plinius SA250 Mk4 and when in class A it generates in excess of 1kw of heat and that is easy to deal with even on the sunny Gold Coast of Australia .To each situation we make our choices 320 watts is not much more than your JRDG Model 8 operating ? 300w-1200w max for your amp is stated in the JRDG manual DaveyF ,I can't fathom your concern if I understand you correctly DaveyF.
I understand what you are saying ,I leave the Plinius in class A/B when it hits 40 deg C only to keep the lady happy as I love the heat ,she does not.Russ, funny you should mention my JRDG 8, because the one thing that I absolutely dislike about it....is the heat it gives off! The amp is too hot to run in the summer months...without using the AC in the room. The room size is obviously a factor, but IME, amps that pour heat into the room and are the size of mini refrigerators are typically more difficult to live with. YMMV.
