    Picked up a nifty little National Studio 10 the other day. It's in great shape and sounds like a wicked little mofo too!

    What an awesome looking little amp! Great score!

    Is there any difference between the three inputs?

    Beautiful! I love the silver-sided '60s cabinets. Looks like it has the original tubes as well.

    Thanks Noah and voojo.

    Hey Noah, know anyone with a schematic? I found what appears to be pretty much the same--Supro model 6606--at Schematic Heaven. Seems about the same with one more input.

    voojo - the input circuit is covered by this shield which is soldered on...so I'm not quite sure; but I can a 100k and a 6.8M resistor and some kind of cap up there so it looks like it might be. It's a little screamer!

    That's probably the correct schematic. I believe this circuit was unchanged for most of the '60s (Valco usually didn't tamper with amps without an obvious reason) and I've seen it under several brands. I also have a Gretsch 6150 schematic which is identical save for a third input with a different resistor value.

    Holy balls you're on a roll lately, Leon.

    Best covering on an amp ever - pimp as hell.

    I've played through one of those once but I think the speaker was toast because it was pretty meek sounding. Gotta love a gray plate RCA...

    Clips!

    Leon,

    That looks like so much fun. Too bad it doesn't have that "Juk'eish" Valco Tremelo!!!

    Cool. I have the big brother... A national Val Trem with two of the best sounding Jensen 10's I've ever heard. That is the very top of the valco line. Same look, same knobs... Mine is a 61 or 62.

    this one is not mine (could not find the right photo) but it looks like this, with a boat load of wear.

    Nice score - that's real purty! I'll bet you can jumper two of the inputs, and use the third...

    Thanks fellers!

    haheh! Yeah I'll get around to some clips. The speaker in this one is mos def alive and kickin! It cleans up pretty good, but man...it can really kick out the grindage!

    Sweet. I've not played that model but I hear you on the Jensens 10s. My old Dan electro DS-50 had the three best C10Qs I've ever heard. In fact, that POS Dano cab was one of the best sounding cabs I've ever heard :eek: !

    Completely unnecessary...any one of the channels on it's own is more than sufficient in the "screaming meany" dept ;).

    After changing out the old Mallory filter cap can this AM, it became clear that the old caps had given up the ghost. With new filter caps, the sound is cleaner and more responsive to touch. Though it still grinds when dimed, the squish is significantly diminished along with some of the dirt. Jumpering the two open channels is now a very useful option ;). So...I stand corrected.

    Mighty quick with the soldering iron! Gotta do what you've gotta do.

    I've found I prefer jumpering channels in my new Vintage 47 Amps Bronson model (Valco/Supro-based):

    I also find I like to run this amp in stereo with my Carr Slant 6V at half-power (fixed-bias, a la Deluxe Reverb). The tight, bright & clear Slant 6V offsets the looser, creamy rich breakup of the Bronson, providing a very complex and appealing mix of tone & texture (sonic creme brulee).

    Not really, I'd set up everything (caps, resistors, etc.) last night. This AM, all I had to do was detach the old and wire up the new. I was actually started working on it prior to my earlier reply.

    Sweet! Bet that is a fantastic combo! Enjoy.

    That National is SWEET!

    Man I never see those old amps around here.

    I think they all ended up at the land fill.

    Too bad.

    OUTSTANDING!

    And the amp sounds really great, too! :YinYang

    Great little sleeper amps.

    Nice score.

    Thanks fellers!

    Very cool looking amp. Do you know anything about the circuit? Is it similar to other 2x6973 + 5Y3 type Valco / Supro amps models, e.g., 1624T? The Supros I've played in that configuration are killer little amps--some of those old C10Qs are just amazing!
