Hi, I can get this Chatham 6080 for about 40$, is that good? Thanks!

@Jason Stoddard hi, i see a lot of big Wima caps in Folkvangr , isn't it used for coupling signal?

can you repost it, i can't see the schematic :triportsad:

Does anyone have the schematic for CTH? I can no longer find it.

Hi everyone Just got alerted to this program by my friend. I too would like to register for a turn to review the unit in Hanoi. My equipment at the moment include: AKG Q701, Grado RS2e and H6. My amp/DAC is just the very basic LH Labs v6, so I'm really looking forwards to trying the PLAY before...

Hi Pete, since this amp use both the nutube for gain and opa551 for output buffer like the sankanagu, do they share any similarity in sound signature?

  Lol, which "very high-end tube amp" did the designer use to make this statement?

Thanks Sodacose, That explains a lot. And some other things i don't understand: 1. The Edcor WSM is 0.5W, does that mean it can only transfer 0.5W of power e.g given secondary tap drving 32ohm load then the transformer can only  pass as much as sqrt(0.5/32) = 125ma, is that right? 2. What do...

Hi Sodacose, That's really nice design and your blog is very helpful for me as well as others who are starting to learn about tube. I have read throughly your Papa Russia headphone amplifier design and i'm confused at this: Assume that you use the 75 ohm secondary tap for 32ohm headphone...

Thanks all for your suggestion, i'm thinking about making a mouting for driver by using acrylic, a local shop do cnc acrylic real cheap. But have you guy ever heard the magnum with just the driver alone? I tried listening to it this way and it sound somewhat better, more air, cleaner but still...

  Anyone have an idea?

I have a Sr325is and i like it a lot so i decided to make my own a magnum hoping that it will be an improvement over the sr325is so i bought v6 driver and a custom wood cup for 40-44mm without knowing it will fit or not. So finally i received the cup, it was made both from aluminum and wood, the...

Does your Pico Power has scratching noise when adjusting the volume?

The 8820 soundstage is wider but the 8920 ss is deeper, the 8820 sounds a bit more clear and balance, 8920 sounds darker, and smoother, more analog like. I prefer the 8920 to the 8820. Btw, i'm from Vn to :)))

Does anyone know the diameter of V6 driver?
