451Not at all the same, but reminded me of this Onkyo basket/magnet design that I've seen on other Japanese hifi speakers
Re: Small questions that don't fit anywhere
452Thanks so much for looking into it for me folks!
I asked the seller; he says they're 'standard 50w speakers that came with the amp' which I'm 99% sure they aren't since they aren't Fane.
The amp is so far pretty cheap, which is why I'm being a bit cagey about it since I do sort of want it...

Re: Small questions that don't fit anywhere
453thanks a lot Nate! since I don’t have the tools to measure THD I will simply try to set all voltages according to the schematic. it’s a little harder to see how P1 and P2 interact with those 25 turns Bourns trimpots than it was with the original 1 turn pots.Nate Dort wrote: Tue Nov 09, 2021 1:10 pm It looks like P1 and P2 are setting the bias point of the output circuit so that it runs in its linear region. You would adjust those for minimum distortion at the output.
Yes, negative feedback is through the other transforming winding and R37.
MJE370 are rated for 25W, so they can get warm without a problem.
here’s a picture of the prototype. added relay switched phantom power and polarity reverse. always exciting to figure that PCB’s actually work the way they should.

454cheers twelvepoint. still super happy that this turned out so well for you. in the meantime I sold one unit to a studio in Toronto. the guy actually once owned a Studer 169 console. so I asked him how the clone compares to the original.twelvepoint wrote: Tue Nov 09, 2021 1:33 pm FM Bassdriver has such great work (and was kind enough last year to help me build my own 169 clone!) and I look forward to seeing this project.
"I think I like this 169 better than my vintage. It’s more open sounding, and the eq seems smoother, very hard to get a bad sound with.
Used it on some over heads with my Soyuz pencils this afternoon got one of the better over head sounds I’ve gotten recently. World clas pre amp you’ve built. I’d buy another one for sure.“
ha, I think we got ourselves some nice mic preamps
Re: Small questions that don't fit anywhere
455Mine is being used for drum overheads too. In my case it's with Oktava MC012 mics with omni capsules and a Jecklin disc.

One small question is the pushbutton +48 and Phase invert switches don't always "catch" and I have to push them a few times. Does this seem familiar, and can I remedy it? For others playing along at home, these switches are lighted pushbuttons, doing some magic that switches relays. Note that this is only a small inconvenience, but I'd address it if anyone has any thoughts, possibly a capacitor value is off?

Personally, I wouldn't tape over the front like some of these suggest. But if you can get it off easily, I'd try putting some sort of insert between the speaker and the panel it's mounted to. Try felt. Cardboard. You get the idea.
The resistor idea is a good one, but I'd be scared of making the little ancient amp work too hard and stop working altogether.
EDIT
Upon closer inspection, you may not have room to do that because the speaker might not be crewed in. This one has plastic tabs melted to hold it in place.
Re: Small questions that don't fit anywhere
457Ok so I know guitar wiring and thats about it. I like the way the spacing is between the frets on a Les Paul standard, more room for fingers than a strat. Is there any company that has this "space" on a guitar that is lighter weight wise then a Les Paul? Jazzmaster?

Re: Small questions that don't fit anywhere
458Incorrect. Gibson guitars are 24.75" scale length (nut to bridge) and many Fender guitars, including Strats, have a scale length of 25.5". Longer scale length means the fret spacing is gonna be a little bit wider.

BUT, maybe what you like is the flatter fretboard and/or bigger frets on a Gibson. If you want a lighter guitar with a more Gibson like neck you should try a Fender/Squier Toronado or Cyclone. They both have 24.75" scale length and a 9.5" radius. Unfortunately both of these currently have vintage style Fender frets. Can't remember what the old Fender Toronados had, but I think they were medium jumbo.
Something like this:

Or just get a Les Paul Special.
Re: Small questions that don't fit anywhere
460There are also a TON of Strat options out there. A lot of the modern ones have a 9.5" radius, different frets, fretboard widths etc. And that's just from Fender...there are a ton of made-to-order replacement necks that can get you exactly the specs you want.
