Starting to prep for a build of the Decware ZKIT, a DIY version of their SE840 amp. Still waiting to hear back from the company whether they’ll sell their UFO output transformers to me to use in building the kit. If that doesn’t pan out, will use Edcor transformers all around. One thing I’m wondering and maybe the crowd can educate me on - the output impedance on the OPTs. Decware’s parts list suggests 6 ohms. My Zu speakers are rated at 12 ohms. Is it better that I choose a 12-ohm output impedance on the transformers? Or just leave well enough alone? And the Edcors are advertising an 8-week lead time before delivery. Yikes.
Otherwise, some parts upgrades I’m considering: a pair of Jupiter cryo beeswax caps for the signal paths and Cardas speaker terminals. Still mulling whether to use two Canadian military spec single- potentiometers - one for each channel - as suggested by @jdsalinger . I personally like dual volume pots, but still going back and forth on it.
Box: Brazilian cherry wood. Top plate: Might order from Landfall, as I did with my Tavish phono build.
I’ll update this thread with pics and maybe any dos/do nots I may run across. And probably will have plenty of pesky questions for @jdsalinger and @13stoploss as I continue. I’m now decently versed in the “how” part of DIY - soldering, sawing , etc. Now I’m dipping my toes into the “why” part of things.
