Nice, I like this look

Thanks guys

My Krell:

Thanks Dr. Gilmore. I'm studying the attenuator

the "Spanish team" is interested Thanks Birgir

Hi Remolon. Thanks for your offer. In this moment I´m waiting for a good box for my Krell. When I finish it, I will send you a MP. It's different EMO. You're speaking about of a highly evolved Dynalo (your current development) and the Krell is disadvantaged. Under the same conditions, SE input/output, single PSU, etc.. Does dynalo is superior? My advice is If you can get one, don´t hesitate.

Good question. I only wanted clone the original... I didn't think on a balanced version

A simulation is just this.. a simulation. I don´t discuss that a "full Dynalo" exceeds to Krell but you should listen this amp.

Nice!!!!

Thanks Dr. Gilmore. It´s only on a channel and I can hear it if I use a headphone sensitive. I get lucky because I bought some THAT340 (around 20 units). I've been changing one by one until I found one that does not make noise but I discarded 10 for this reason I believed that the THAT340 had a better quality

Hello I can hear a little "ufffffff" without music on a channel (Balanced and SE output). I read that normally this type of noise is associated with the input transistors. In this case, Is it possible to be produced by the THAT340? Regards

Quite small, nice job !

Thanks Dr. Gilmore.

Hello guys. Thanks for your replies. Dr. Gilmore, I never use IEM´s so I haven´t got any problem, but I´m thinking about a new match. Nopants yes. I have a KSA 5 Klone and the original use a XLR male conector for the output. I used a 4 male pin conector for the output (more or less similar to original).I want to use only a connector for my HD6X0 headphones. I know it´s not correct but I have a cap for this conection in case I don´t use it. Well, I´m not good describing the sound of my amps (and my natural language is Spanish) but I really like the dynahi sound. In this moment I prefer the Dynahi sound to Beta22. It´s very clear and powerful, on this point is similar to my Beta but the great difference is that the Dynahi have a detail, a note... what really, it make it very different. A PSU picture. I use two Sigma22 and two 160VA toroid

Hello Dr. Gilmore. Your are right but If I connect the servo and I take a measure, I have DC offset around the same 70 mVolt in + and - channels but it doesn't have drifting. Possibly this is silly but I worry break a headphone with this offset. A picture of mi Dynahi.

Two week burning the amp. I took new dates. L channel BIAS ~ 0,750 mVolt. Offset ~ 2 mVolt (Without servo) R channel Bias ~ 0,750 mVolt. Offset ~70 mVolt (Without servo) I've tried down the offset of the Right channel but I can´t. This channel always has a hard drifting. If I regulate the + channel to 0 volt, the - channel drifting to 150/-150 mVolt. If I tried the other cannel down to 0 volt, I have the same result. What can be causing this problem?

The Opa 445 can reducing the offset from 100 mvolt to 0 Volt?

For the LCD2 don't is a bad amp, but I prefer use it with Monitor 10 or the HD6X0, DT990, DT880... IMHO, the Beta 22 or Dynahi balanced is best option for the LCD2.

Hi I´m looking a set of KGSSHV boads. Please, if someone has boards... Thanks

Hello It´s balanced input and unbalanced output.

New dates: 1Khz, 1 Volt Rms to input Out put: 17,138 Volt Rms Thanks

Dr. Gilmore You are right. For an error I mistook the cap. value for 0,2uF Now my Dynahj is flying I wish you a happy new year.

Thanks Dr. Gilmore I will check the cap. tomorrow. I suppose that it´s the correct value but... Sincerely, I will prefer a simple error on the caps code. We buy a big lot of Mospec and after "match", they are working fine on the Krell, but I will take note... Thanks

ok, Thanks Justin, the next time. I checked the boards but the resistors values are correct wiht this: I only changed the cap. for 1000 uF/35 volt Yes, I had problem with the offset but I could solve with patience... and a matl whisky. Thanks
