SilverTone 1482_esq

Callin’ this one worthwhile.

Thanks to Platefire for going 1st, and Sluckey for the artwork n more.
I always name them after climbs, This one; “A Christian delight” 5.4 Seneca Rocks WV.  You’re only 200’ from the horizontal plane, but it feels and looks like 1,000 feet of air!

After 10hrs, 5 guitar, 5 audio, this gets high marks for living room versatility in a "blue collar" home.   :laugh:
If you deal well with monaural, an AU7A in V1,  2 bookshelf speakers, reasonable volume, done.

For guitar an AXWA get’s you from early Sunday to Late Friday sounds.
Speaker impedance tests best at 14-16 ohms both scope and ear.
Note: late Friday sounds can only be had at house volume,
cleans can be had at bedroom levels.

I’m confident that once the Tremolo is working it will just add to the versatility.

This is NOT a by the numbers build, or a daily gigg'r, I’m ADD, no pdfs
But if the tubes are just laying around n you need another amp…….

I can’t prove it so it ain’t so, but, I think the low Z, high Z thing
has mojo  :icon_biggrin:
Rev 1.4 below is the most resent schematic.

NOTE: updated schematics to rev 1.5

So, does the trem work?
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Version II paperwork

6K6 and 6V6 produce the same "range" chime to grunge.  The 6V6 and 50vdc B+ bump, moves it to the full on 12W amp from 6K6 8W practice amp

"A Christian Delight" I Like it! but why have you not posted a gut shot :dontknow: Also I was trying to figure outhow you accomplish the 12VDC increase for 6V6? I don't see any circuitry to switch the voltage. Glad to see the1482 is living and growing. I just discovered this and still absorbing this. I'll have to check out the thread you linked on this. Great Job there shooter :happy1:
On the right track now<><

The climb was one of my all-time favorites.  The original climbers name was Christian, I believe he intended it to have the "dual" meaning after the climb.  :icon_biggrin:


if you move the B+ tap to the right of the 750ohm PS resistor, that's the 6K6 "setting".


It's a good "room amp" with either tube configuration, the trem was fine at lower volumes, but past 7 it lost out to the main signal.
since my guitar is broke and I needed another audio amp, this filled the bill.
here's the gut-shot awaiting the roach, I believe the rest is wired.
