Symasym - the sequel

[Colescuttle]

Physician, heal thyself.

The best price for the (in stock) Toshiba transistors used in the sysm-asym can be found at https://www.bdent.com. 25 at 0.65 USD apiece. Don't know what's up with Digikey.

Hmm, i see 2.20$ for 10-24 pieces... might have been a typo?
Digikey has 1.98$ for 10 pieces.

Try the following, but .73 rather than .65.

More boards and DUMMY WARNING!

I'm putting a chassis together for my sym-asym. Is this an amp that would benefit from being left on all the time?

Ryssen:

If you're within two boards of a price break point on the number of boards that folks want, I can take another two. Either I'll do something dumb and need a spare, or, if this amp is as good as I anticipate, I know someone who'll want me to build her one.

Hi George,
No amp will gain from being left on all the time. The only things that stay on all the time (save the furnace, fridge, stove and water heater) is my server and the oven in my HP freq. counter. Everything else gets turned off.

Thanks, Chris.

Needed to know how accessible to make the on/off switch.

They are still dropping in..
In a day or to,I will mail the zip file to the maker,and ask for the price and shipping from him to me.And I want you to mail me your name and adress,and I will calculate the price for boards and shipping to your country.
And also write down if you changed your mind and want more boards.

Request for AAK.

Hi, Al:

Could you post the Eagle file of the schematic that shows component designations as listed on your BOM, or point me to where it might be found?

Thanks.

George

Hi Colescuttle,

Here's the schematic from Mike's symasym site. To make things easier I labed all components on my board according to his schematic.
If you need the PS schematic let me know. I did post it on this thread somewhere.

[AAK]

Hi Ryssen,

Sounds like your a little confused. Are you ordering my board, or Mike's found here?

http://www.lf-pro.net/mbittner/Sym5_Webpage/symasym5_3.html

 

[Ryssen]

No it´s your board!
I have the sa50d.zip
And the symasym_aaks_pcb__bom.pdf
But I don´t have the schema..

 

[AAK]

For the amplifier schematic check post #313. The PS schematic is down below.

 

[Ryssen]

Okej,now I feel better..

If I later on want to try j-fet´s at the input it would nearly be like plug ande play,or wont it?

There was some advise in http://www.diyaudio.com/forums/showthread.php?postid=1072382#post1072382
to.

 

[AAK]

Ryssen,

You might want to check to make sure that everybody is in agreement to which board there going to get. There was some question whether to build mine, or Mike's version 5.3 which has been heavily tested.

If you go ahead and order my version, I'd like four boards.
