Title: SE84CS
Post by Steve Deckert on 04/18/08 at 01:20:01

The SE84CS 2001~2006 Also known as the "Select", the SE84CS was a tweaked out SE84C in a black chassis.

Replaced by the SE84ZS in 2008. https://www.decware.com/newsite/SELECT.htm

Below is an excerpt from the original web page:

This amplifier, as well as the the gray ones, has optional hardwood bases available. We still make these even though the amps are discontinued so that someone buying a used Zen can still enjoy the option. These are available in walnut, cherry, oak, maple, and custom exotic woods on request.

We also did several one of a kind custom SE84CS amps such as the one below with color changing paint. It changes from black to purple to blue to maroon depending on how the light hits it.

Aaaah... my pair of Selects have been with me long enough to be "older gear". I believe that is a GOOD thing, as I am still absolutely loving these amps.

Steve,
I had e:mailed you a while back about a "check-up" for my amps, and I have been too busy to get them boxed-up and sent in. I will be doing that in the next few weeks.

Basically... I need to have the following checked-out, and see if I can do a few nice little mods to them:
1) Moderate hum issue both amps.
2) Loose binding posts on 1 side of each amp. Is it possible to upgrade these to the metal versions on the newer models or something similar ?
3) One amp, the front input RCA s are loose. I know this is contributing to hum on that amp at least. Are there any upgraded ones you can recommend/use ?
4) Will you still "permanently strap" these amps for monoblock operation ? The little strapping wire and Y cables bug me. Also, following up to #2, I only need 1 set of binding posts, can you install 1 set(left on left amp/right on right) and put a blank plate over the other ?
5) Tube sockets. I know for a fact I have one very loose socket. Are the ones on the new amps the same ? Any recommendations for an upgrade here ?
6) V-Caps. Do you offer a V-cap upgrade ? Will you install them if I ship them with the amps ?
7) What is the weight of an unladen sparrow ?

Any other tweaks you might recommend ?

By the way. I am ordering a Tori II sometime in June for another system. I am frothing at the mouth on that 8-)

Hi Steve,
very nice indeed the Select been with me since 2004 and the serial no.238 that sound warm and like to keep it forever. Lately I have a problem with the amp that fused when I switch on a number of time.I presume there is a short in the power transformer.Anyway I am a Malaysia and I managed to ask a local technician to check and he told me the wire had been short and do not know the value if I have to rewind the trans. May I know the voltage and milliamp on the pin 4 and 6 on 5U4 tube. Look forward to hear from you,thank you

cheers,
kh chia

Remove the rectifier tube, replace the fuse, and power on. If the remaining tubes light up, then your amp is likely just fine.

I am the original owner of Select #240 born in May of 2004 and it is a giant killer, always has been. It is well seasoned - 10 years!

Honestly I am really eyeing that new Super Zen Select with the meters, but not ready to jump yet.

I only have one pair of the original SV83s left from a large purchase years ago and will soon need to order some backups.

I have been away from this forum for a few years but notice the original SV83s are gone and the new ones are not correct.

What is correct output tube in 2014 to stock up on for my amp?

From the SE84CKCS web page:

"This amp is shipped with premium quality N.O.S. 6P15P-EV output tubes with gold grids rated at 5000 hours. These Russian military spec tubes are the top grade of what we came to know in this country as the SV83."

I would think that you could use the 6P15P-EV in your Select without any issues. You could talk with Decware and ~~other~~ [order] the tubes from them as well.

Thanks buster, this is my third Decware amp, and I fully understand the specs. I was more interested in avoiding things like the SV83 tubes currently available (listed as 6P15P-EV) that Steve said were not appropriate.

Steve has a line on some of the best tubes available for these amps. Just get them from him - he'll make sure the are properly tested and matched. (he does that all in house)
