tube fanatic Posted September 24, 2018 Share Posted September 24, 2018 Their amps look interesting. Has anyone had experience with them? http://whammerdyne.com/ Maynard 1 Quote Link to comment Share on other sites More sharing options...
joessportster Posted September 24, 2018 Share Posted September 24, 2018 Cool looking amps and pricing looks decent, not sure how many may have had experience. looking into it they are asking 50% down with delivery in October and they are calling it initial pricing 1 Quote Link to comment Share on other sites More sharing options...
Schu Posted September 25, 2018 Share Posted September 25, 2018 How is the direct current handled without a coupling capacitor. Quote Link to comment Share on other sites More sharing options...
windashine Posted September 25, 2018 Share Posted September 25, 2018 under the design process tab, is this picture - I'm thinking those aren't fuses.... 1 Quote Link to comment Share on other sites More sharing options...

I am familiar with the schematic of direct coupling but Maynard will have to answer the question of how. Personally I have no problem with a capacitor.

No, they are power resistors. At least that is what I think you are talking about. It appears that solid state devices are used in the circuit judging by the device that has a heatsink. Could be a regulator or some type of constant current source. My guess would be a constant current source. Nice looking film capacitors.

KlipschFan61 Posted September 25, 2018 Share Posted September 25, 2018 Stylish looking gear for sure. I like their naming conventions. Quote Link to comment Share on other sites More sharing options...
tube fanatic Posted September 25, 2018 Author Share Posted September 25, 2018 They claim to be using multiple regulated power supplies for all circuits. As for the direct coupling, that is a common practice among some designers- the plate of the driver is connected to the grid of the output tube. Personally, I don't like to put high voltage DC where it doesn't belong and won't use that method. I have no problem with coupling caps and do not find that they degrade the sound. They are vague as to exactly what they are doing but it strikes me as being a servicing inconvenience for anyone who has to work on their amps. Look at the "functional diagram" on page 4: http://whammerdyne.com/wp-content/uploads/2018/04/2018-04-07-Whammerdyne_Owners_Manual.pdf Maynard Quote Link to comment Share on other sites More sharing options...

thebes Posted September 27, 2018 Share Posted September 27, 2018 $13k! I know your looking for a technical discussion, but those things are butt ugly. Look like some of the gizmos you see in the hospital hoooked up to patients. Some of the salesmanship is spurious too. " Class AB switching artifacts, Class D high-frequency noise of transitions between output pairs of devices." Huh? There are limitations and imperfections in anything in life, not only circuit topologies. But are they saying a $13k Class A/B or D (not that there is a $13k Class D) cannot match a $13K Set?

Shakeydeal Posted September 28, 2018 Share Posted September 28, 2018 Some of the amps are affordably priced. I would not be a buyer at 13k, but the ones under 5k lòok very interesting. Shakey Quote Link to comment Share on other sites More sharing options...
justinsweber Posted September 29, 2018 Share Posted September 29, 2018 Ive heard at several shows at they were amazing. Can speak beyond that, but at the time under show conditions there were impressive... never in a large room but still impressive. Quote Link to comment Share on other sites More sharing options...
garthbernstein Posted February 16, 2019 Share Posted February 16, 2019 I have the DGA1 (entry level), I'm very happy with it paired with souped up La Scalas (ALK engineering crossovers), the mid-range is super strong, and the ALK crossovers add depth and more bass (plus a good sub) = I'm very happy Quote Link to comment Share on other sites More sharing options...
