Well I decided to build one of these amps because it should do exactly what I need, I went with the single choke version and I am pretty excited to hear it and all I am waiting for is my EL-34s. I am glad I found the YouTube series and this website, its such great content!, Now I changed things up a bit and went with a bigger chassis and used Hammond output transformers because to get the Edcors into Canada would kill me with shipping, exchange, duty and whatever else and the Hammonds are quite a bit bigger and 11lbs each haha. Went with wood sides for a more vintage look. I have some tube experience but never did a full on build and it was awesome! I added some photos, I centered the driver tubes in-between the choke and end of the chassis and centered the power tubes with the output transformers. Once I confirms everything is good and play it a bit on my smaller speakers I'm going to hook it up to the Klipsch Cornwall 3s and see how she does!
