Kevin,
How much for the digital kit?
Don't know yet..... should be in the $500-$600 range but Hypex is changing prices by swapping an opamp on the input an the exchange rate is not exactly favorable at the moment so I'm not sure exactly where the price will land.
How big are the transformers on each?
In the UCD 180 version shown uses 250VA transformer. It only needs about 100VA per channel. The UCD400 will use a 500VA transformer. Both 250VA & 500VA are more than enough if you use a quality transformer.
How much to assemble each?
They are a kit. All of them will be kits as I'm not getting into the finished amplifier business. We will continue to focus on very easy to build kits that introduce more people to the joy of DIY.
It isn't real labor intensive so figure 3-6 hours depending on how fast you work, tools available & experience.
Would assembled amps include a warrantee?
The kits come with a parts warrantee just like all of our kits.
$300 for the 60 wpc chip amp seems very reasonable if everything is included.
It is very reasonable as my parts cost on just the amplifier chassis, Cardas inputs & speaker post etc... is about half that amount. The goal is to have one inexpensive entry level unit to get new people involved in DIY. I think Doc B has done a great job of introducing new people to kit building by offering the Foreplay at such a low price that people are willing to take the leap of faith and build it because they are not out much money if it goes bad. Same idea with the $300 LM4780 amplifier. For $300 I'm hoping a lot of people will take the leap and build their first project.
