Smeggy Posted March 21, 2009 Report Posted March 21, 2009 That EHHA is cheap as muck and will run off my Beat 22 psu! I like that idea, I could have one PSU running 3 amps
Smeggy Posted March 21, 2009 Report Posted March 21, 2009 Is the EHHA in the same ballpark as the SOHA for sound, I guess they're similar prices once the EHHA psu is added.
dBel84 Posted March 21, 2009 Report Posted March 21, 2009 I prefer it over the SOHA II, but this is a personal thing ..dB
Smeggy Posted March 21, 2009 Report Posted March 21, 2009 that's what I wanted to hear Now, how to squeeze a B22, DynaFET and EHHA in one case.... must find huge case with dividers.
Guest sachu Posted March 21, 2009 Report Posted March 21, 2009 that's what I wanted to hear Now, how to squeeze a B22, DynaFET and EHHA in one case.... must find huge case with dividers. hahah...yeah taht would be some amplifier to lug around.. about to send in my BOM to Jeff for the EHHA
Smeggy Posted March 21, 2009 Report Posted March 21, 2009 Cool. I figure it'd be easier to lug one amp rather than three as long as I fit it with some big-ass carry handles. Mind you, it's not like those three together would weigh much, just need to be careful with spacing and ventilation. I reckon one of those bigger dissipante boxes or similar should do the job.
Guest sachu Posted March 21, 2009 Report Posted March 21, 2009 Yeah..if you are going to be using standard BOM heatsinks then it would be easier i suppose..However, if you want to use bigger off board heat sinks, then you need to get more creative..not that you have any problem there..
dBel84 Posted March 21, 2009 Report Posted March 21, 2009 I am interpreting this 3-in-1 idea as smeg and about as useful as the classic lubricant Using a single S22 makes sense but will limit the use of any one amp at a time. Also bear in mind that the EHHA has tubes which need a heater supply - a simple regulated supply will do although it was proposed to use the sigma 11 for this purpose. I should also qualify my earlier statement of my preference over my SOHA II = my SOHA II was a very early proto and significant changes were made to both the proto and the final release, thus mine may sound different to the version that is now in common circulation. ..dB
Smeggy Posted March 21, 2009 Report Posted March 21, 2009 Nope, perfectly serious. I need to keep box count and wires to a minimum. I will only be using one amp at a time and that will also cut down costs significantly as I'm going to have 3 amps that ideally need a s-11 so to me it all makes perfect sense as long as I go about it properly. It's going to be running a wide range of phone types and allow me to have a trio of great amps I'd otherwise be unable to pull off financially. It's a win project all around with no downside from my perspective. Plus it'll be both tube and solid state. One other reason I want a big boxis that I want to integrate Stax and Sony transfo boxed in it as well. I'm basically looking at a all-in-one super package to last me forever with superb flexibility and sound. That's not too much to ask is it
wiatrob Posted March 21, 2009 Report Posted March 21, 2009 meh..well its a desktop class 2 transformer..puts out 1.67A..way more than that specified which is about 0.8A..so i hardly doubt that it is the transformer.. I'd agree with you NoNoNoNoNoNo. If it was a DC wallwart, I'd be suspect. But it's just a transformer. One of these days I'll get a nice toroid on it and see...

Hopefully
dBel84 Posted March 22, 2009 Report Posted March 22, 2009 I thought I would post the (pictoral) journey of these amps, seeing as it has finally come to an end. Boards etched The power supply initial testing laying out the top plate wiring up Earl's input stage top side The panels arrive and a quick dry fit The assembly JP EC Under the hood Final result and this is where JP and Earl need to pick up ) ..dB
Guest sachu Posted March 22, 2009 Report Posted March 22, 2009 That is just totally wicked Don... Oh and by the way..the Stacker rules..It is just on another playing field. We missed you though..another time for sure..just don't let go of that stacker before calling me first
Guest sacd lover Posted March 22, 2009 Report Posted March 22, 2009 What a beast! Seriously great work. I cant wait to get my hands on this beauty. There are going to be some serious hybrid comparisons going on .... followed by some showdowns with my tube amps.
devwild Posted March 22, 2009 Report Posted March 22, 2009 just don't let go of that stacker before calling me first haha, he may have a battle on his hands if he ever did
jp11801 Posted March 22, 2009 Report Posted March 22, 2009 Hopefully after I get my hands on mine a few Bay Area folks can give it a comparison.
dBel84 Posted March 22, 2009 Report Posted March 22, 2009 Looking forward to hearing other people's views , rather than hearing my monotone ..dB
dBel84 Posted March 26, 2009 Report Posted March 26, 2009 the last picture i am going to be taking what could this mean ..dB
Smeggy Posted March 26, 2009 Report Posted March 26, 2009 My guess, a couple of very happy faces Fine packing!
Guest sachu Posted March 26, 2009 Report Posted March 26, 2009 oh crap..does this mean I will have to return the stacker to you now Don
dBel84 Posted March 26, 2009 Report Posted March 26, 2009 well if you pick up the EHHA I will have nought left ..dB
