JBLoudG20 Posted July 2, 2007 Report Posted July 2, 2007 Hey Kevin: how is this amp progressing? Last I read you had build a proto and seemed happy with it. Was that last board layout tested? I'd like to give a hand testing if needed.
kevin gilmore Posted July 2, 2007 Report Posted July 2, 2007 prototype works absolutely fantastic. Latest board layout at headwize.com in the thread. I have not had the time to verify that final layout completely yet. Sure would help if someone with much younger eyeballs would look at it and make sure it is correct before i spend $500 on boards.
DigiPete Posted July 2, 2007 Report Posted July 2, 2007 Kevin, What are your impressions of the Dynafet vs. the Dynahi, sound wise?
JBLoudG20 Posted July 2, 2007 Author Report Posted July 2, 2007 I'll start checking the layout for you Kevin. My eyes are still pretty good
kevin gilmore Posted July 2, 2007 Report Posted July 2, 2007 The dynafet has that slightly sweet almost tube like sound that only fet outputs can have. But because of the drive circuit it has the balls of no other fet output amp i have listened to. If you want to buy one, you will have to find someone willing to build you one. And as usual there is a whole bunch of different ways to build this thing.
postjack Posted July 2, 2007 Report Posted July 2, 2007 If you want to buy one, you will have to find someone willing to build you one. Done! Now bring me a shrubbery!
Mister X Posted July 4, 2007 Report Posted July 4, 2007 Sure would help if someone with much younger eyeballs would look at it and make sure it is correct before i spend $500 on boards. looks good to me.... and since we moved Imageering allowed me to make a new account and they said I will get a second order rebate. How many prototypes you wanna order? (i punched in a quote for ten boards and the price was only $17 each but I guessed at the board dimensions so.....)
kevin gilmore Posted July 4, 2007 Report Posted July 4, 2007 Board is 4.95 x 5.40 inches, 302 holes. I'll take 5 boards please...
JBLoudG20 Posted July 4, 2007 Author Report Posted July 4, 2007 It looked good to me as well. Mind if I hop in for a few boards?
DigiPete Posted July 4, 2007 Report Posted July 4, 2007 I'd be interested in 4 boards as well if this is turning into a group buy
Filburt Posted July 5, 2007 Report Posted July 5, 2007 What's the estimated build cost on this thing?
JBLoudG20 Posted July 5, 2007 Author Report Posted July 5, 2007 http://headwize.com/ubb/showpost.php?fnum=3&tid=6584&pid=59001&fpage=4 According to that link: 50 plus PSU, Case, board, and all casing extras (pot, switches, RCA, 1/4"), plus heatsink
kevin gilmore Posted July 6, 2007 Report Posted July 6, 2007 that is the seriously shrunk down version. The real thing costs a lot more. I would be happy to tell you the real cost, but as usual i don't have the faintest idea
bhd812 Posted July 12, 2007 Report Posted July 12, 2007 that board looks so easy from the pic..its like a drop and play deal.. damn me! for no reason.. i want to hear one really..
DigiPete Posted July 12, 2007 Report Posted July 12, 2007 me too !! Come on Kevin, give us a Dynahi beater
aerius Posted July 12, 2007 Report Posted July 12, 2007 that board looks so easy from the pic..its like a drop and play deal.. Piece of cake, if you can handle soldering a bunch of SMDs. Most people can't solder SMDs, especially not the fun stuff like smaller chips and transistors.
DigiPete Posted July 12, 2007 Report Posted July 12, 2007 Yeah, you definitely want the through hole variety boards...
JBLoudG20 Posted July 12, 2007 Author Report Posted July 12, 2007 Yeah, you definitely want the through hole variety boards... I'll take any variety boards!
Mister X Posted August 9, 2007 Report Posted August 9, 2007 Ooops, seems someone totaly forgot about this. $15 each if "we" order 25 of them.
Killercrush Posted August 10, 2007 Report Posted August 10, 2007 I'm up for one if somebody can build it for me haha
DigiPete Posted August 10, 2007 Report Posted August 10, 2007 well, I would get four for a balanced rig..... only 21 to go, come on guys!
Mister X Posted August 10, 2007 Report Posted August 10, 2007 Have a reliable source for the 2SJ109 & 2SK389 s? Cause that appears to be a major stumbling block... (I have not been able to get a hold of Dan to see if has enough inventory)
