My dynalo

Can I change that340 or 2sk170/2sj74 for ksa992/ksc1845 or ksc1815/ksa1015? I need to do an order on Mouser, so I can add this fets on my order.

I like Nichi KW... but really, you can put anyone

Vinyl... I love "Brighton Rock"

Thanks Dr. Gilmore !

Can I replace the OPA134PA in the GRLV with a DVR134PA?

Guys... you're killing me!

Sorry but, but... 500$ for a SR007A? Where?

Happy Birthday

Maybe for this ¿? C2M1000170D http://www.mouser.com/ds/2/90/2m1000170d-838564.pdf

if you can uses Jfet .

Hi I read all thread and I though that all resistors was necesary. I use this GRLV with my Dynalo SS. I didn´t any adjust (I matched all resistors, leds and I adjusted trimpots on 50K before plug in). With the Dynalo SS connected to this, I can measure; -19,993 volt and +20.000 volt and between rails 40,00volt exact. With no load, same measures.... I hadn´t noises or issues. I´m using a r-core with 25Vac@1Amp x2

Oh no! please Dr. Gilmore... I just finished doing it .

My Dynalo SS lives too. My amp runs with 20Vdc rails and 255R Bias resistor and like Pars, I use Jfet (2SK170GR/2SJ74GR) instead That340 (I learned the lessond with my Dynahi). I measured 160mV at cold start and after 20 minutes my amp is stable to 0,205mVolt (around 10mA) with an offset of 0~4 mVolt. Transistors temperature is 35º and 40º. I read all thread and on speciality this answer. I´m going to change R255 for other value around R280.

Happy Birthday!!!

I have this Amp. We used Wayne desing but doble mono configuration. I did my amp last year. I

I'm waiting for a pair of "Pars bridge's" [emoji6]

Thanks Dr. Gilmore !!

Thanks guys. I usually solder smd with a "normal" size but I never solder any with a long legs. I tried with a 60w iron (a few second), solder paste and I guess that I have good result.

Like the Dr. Gilmore

Novice question: What is the correct way to tin this type of pad? Should I fill with tin or just put a little under the component as I normally do?

No Kit is offered. A GB was made two or three years ago in DIYAudio and the PCB´s after many delays arrived earlier this year. PCB was designed to be used in this kind box.
