Alamo Embassy (2563) Amp Schematic ??

[LooseChange]

Small amp with a 5Y3, 6V6, 12AX7 and a 6AV6 (tremolo).
Volume, Tone, Speed and intensity.
10" Speaker.

Thanks!

Somehow I put this in the wrong place.
Still can't find a schematic. Anyone?
Thanks!

I think Alamo schemos are had to come by.

LC, I googled last night for a bit, couldn't find nuthin but guys talking about their Alamo and not being able to find a schem. Sorry!

[LooseChange]

Thanks for looking.
It's a small enough amp that I was able to troubleshoot without issue.
The amp is working really well now.

I've got like four here, but none for the Embassy. (Capri (2360), Fiesta (1962), Jet (2564), and Montclair)

[LooseChange]

Any of those amps run the tremolo with a 6au6? I'd like to see that.

this one runs 6Au6 for trem osc...

good luck with you're quest.

Lessee....

Capri... No... 12AU6 input, 50C5 output, 35W4 recto... like a cheap Kay or bargain basement, but has a tranny that isolates it from the mains (and a tap on the secondary HT to run the series heaters)
Fiesta... No... 12AU6 input, 50L6 cathode biased output, 3525? recto... 12AV6 trem... (wiggles 50L6 g1)
Jet... No... 1/2 - 12AX7 input, 6V6 output,  5Y4GT recto... SS reverb, other half 12AX7 & SS trem.
Montclair... No... 12AX7 input split for 2 ch, 12AX7 in a cascode config? on second channel, 7199 PI, 2-6V6PP output... 12AX7 trem on second channel.

<Attached: Montclair schemo that I have... I think there's errors in it too>

> Montclair... 12AX7 in a cascode config?

No. Both units shorted grid-plate: diodes. Also note DC voltages near zero.

Diode modulator. Trem signal is applied out of phase, no thump, but diodes cut-off and block signal.

Possibly an evasion of Fender's patent. Or "good idea" for thumpless low-level modulation. Must say I've never seen it before.

Must say I've never seen it before.

OK, so please tell us more? Maybe a good thing to add to all us trem guys?
