Ok thanks for the explanation.

Hi thanks for the replay. Yes it’s very confusing, so I will try the 10963w2. What about the newest firmware for the CPLD which one is it? Seams there’s no rhyme or reason. Not sure what you mean by “you can get 2003be from the same 117 for 1099rc1” Thanks

Hi, I have a usb board firmware update question. I followed the process and no problem at all updating . I just wanted to know which version is the latest for cpu flash, I used 1096c. There is also 1096c4w2, 10963w2, 1096d_RJ. Could someone clear this up for me? Thanks

Hi all, I have had the Lks 004 Dac for a few weeks now and for the most part I am very pleased. The only gripe I have is, it keeps loosing the lock after its on for a while. I placed a small fan blowing on the Dac chips and problem went away. I also find that the two heat sinks furthest to the...

Thanks for clearing that up. I was running the amp at around 250mv that's why it didn't sound right. Every thing else checks out in the troubleshooting guide. Also I had the power supply set at 24v not 29v. Supply 23.88v S1+ to S1- 23.08v DC offset input to output gnd .02v V+ to V- = 21.8v on L...

Hi thanks for the reply. I should have some time this weekend to go through trouble shooting guide. I will report back with my findings. Thanks

Hi I just completed basing to class A. I am having a few issues one is not being able to get down to 1 mv across R10, the lowest is around 2mv with 627/637 and around 4 mv with ad 8610. Amp does not sound right. Here are some measurements and parts used. I am also using bass boost alps 50k pot...

Never mind sorted it out bad power supply ground.

Hi Back again not having much luck with this build. The amp stopped working I am getting a loud hum. I think the problem is in the ground channel my supply voltage to opamps is 13.6v which checks out on pins 2,4 and 7 except for pin 2 on ground which is high at around 19v, pin 3 and 7 is 13.6 on...

Yes I am hooking it up with wires it's not a board mount. I agree it wouldn't be wise to install it on the board only to remove it in a few days. So my question remains is it ok?

Thanks I missed that. I am waiting for the 50k pot to come I have a 100k pot on hand is there any harm in using it till the right one comes?

Hi sorry for being so vaig . I was measuring dc volts at R24. Anyway it turns out I had a 1M resistor in R13 instead of 100R not sure how that happened. I changed all the transistors just to be sure and all is working fine. I noticed that there is an additional .01uf cap on c2 why was this...

Hi all I just built a PPA v2 that I had for years with my spares. I cleaned the board off it had some oxidation. I am having a problem with the ground channel no voltage when trying to adjust buffer bias. Both the left and right channels are fine and voltages to the ground op amp are correct. I...

What build do you guys recomend for the HD800, Mosfet, BJT's, Caps??   Thanks

Hi anyone know I could find a pair of the denon ah d7000? Does that shop have any more? Thanks Frank

Pitures Please

thanks again one more question could tube be damaged if used?   Thanks Frank  

thanks for the reply can it use a 7316 tube or tubes?

I am not sure what type of amp it is, if anyone knows of it could you let me know. Also what type of tubes it takes. Can it use a  5960 / 7316 tube. I ask because sold some tubes that left hear working and buyer says one does not work. but he was very reluctant to give information about amp used...

Amb is top notch, I cant wait for his next project. Thanks Ti for all your help Frank

very classy design, well fitting for the B22

I just finished my Y2 and I must say I am very happy with the way it sounds. I have it matted with a Y1 full ++, great job guy's thanks for the out standing kits. Frank

Thanks for the info Frank

Can I ask where you got them I need to repair a cardas cable? thanks Frank

Hi anyone have a source for a good quality 16 ga hook up wire by the foot for a B24 Amp? I need three colors. thanks Frank
