If you're going to do a blog on harp amps, learn something about amps.

"It uses relatively low voltage power tubes, which means it might be good for harp. Lower power means sweeter tone and less feed back."

It's a low-wattage amp, which is not the same thing as a low-voltage amp. Learn the difference. And the first thing the author states is that this is a high-gain amp (i.e., a lot of pre-amp gain), which is bad for harp and generally triggers feedback.

"It may be just as easy to build a deluxe or bassman clone (I suggest looking at a tweed Fender Super Amp)."

Do you have any idea at all how amps are built? A four-input amp with a midrange and presence control (i.e., a Bassman) is going to be harder to build simply because you've got to string wiring to all of those jacks and pots. The tweed Super is very similar. The tweed Deluxe is simpler -- it uses a single tone control and two volumes. Don't even get started on blackfaces with reverb and tremolo circuits.

You really need to bone up on some amp primers if you're going to dish advice.
 

Pay attention to what I wrote. The amp in the project uses 6DG6 tubes and the power transformer puts out only 200 volts. That's low voltage for a guitar amp. The preamp stage is high enough gain for a guitar amp, but a harp player would put in lower mu tubes.

I've built many bassmans and the stringing all the wires is not a big deal. It just takes a little longer. I've wired a bassman in about an hour.

Why would you post like this if you haven't read the article and obviously don't know about amps?
