Ordered a Willsenton R300

Ibought a Wells Audio Innamorata SS amp earlier this year -- by far the greatest SS I have ever had, and by memory I thought it might be more revealing than the Kootenai. I swapped them recently and it took just a few moments to realize the Kootenai was much better

I’m not surprised.😊

It will be interesting to see how the Kootenai compares with the Willsenton  R 300 and definitely Don Sachs’ new 300b push-pull amplifier. Fun times ahead.

I also think the R300 has a fairly good chance of working with my JMR Offrande speakers.  A few years ago I built the 8wpc Nelson Pass AMP Camp Amp.  The Offrandes were not happy with this pairing.  They sounded decidedly underpowered.  However, I also tried them with another 8wpc amp, the Antique Sound Labs Wave 8.  Some of you may remember this one from 2002.  They were sold for $98 each for a pair.  They came with ECL82 tubes.  The Offrandes sound great with those little amps.  I rarely had to exceed the 9:00 position on the volume control.

If the Willsenton R300 has at least decent quality output transformers and power supply it should be okay. If good rather than merely decent quality then should be quite good sounding pairing.

will also depend on their output caps.  The photo showed what look like your typical $5 Chinese MKP caps with their fancy labeling.   Klipsch used caps that looked like that in the Cornwall IV crossover.   Changing them to something like a vcap odam will make a very noticeable improvement, but as charles1dad said, the iron will matter.  Also the fact that they driving a 300b with a mediocre driver stage will limit the whole thing...   Honestly, they could build the same amp at a $100 higher price point and improve it considerably just looking at the photo....

I absolutely understand that observation.

When you price an audio component to meet a strict price point, corners will inevitably be cut somewhere. Word of mouth feedback says that this is a good sounding amplifier despite it’s very low price (For a 300b SET amplifier). However if the building blocks (Output transformer and power supply) are good, you can improve things noticeably with better quality capacitors and tubes.

My suspicion is that the Willsenton R-300 probably has good quality transformers and power supply even at the modest price point. They probably cut cost via cheap resistors/capacitors. That’s OK these can easily be upgraded if one chooses to do so.
