Who made this amp?

Picked up this 1 tube 6je6 6lq6 amp. Extremely clean. Would like to see if there is a schematic out there for it. Only markings are Little Willie on the face and KTI on one of the circuit boards. SSB delay works but is way to short so will have to up the cap in that circuit I am guessing when I recap the unit. Also need a 12V bayonet style bulb for the meter. Had a 6v from a Browning but way too bright. Anyone know the number for the 12v version? Nothing on bulb but 12v. Any info on this amp good or bad is greatly appreciated. 20200501_185559.jpg

Sorry. Your pictures do not jog my memory. Back in the late 70's and early 80's, many folks were building tube amplifiers. Some sold more than others and those are the amps that are a easier to find schematics for. Not unlike transistor amps today, most are copies of one another. You could probably search the CBtricks website to find a 1 tube amplifier that is close enough to your Little Willie to enable you to service it properly.

Below is a schematic of a PAL brand Base (AC powered) amplifier. Though it does use a driver tube, chances are the internals are very similar to yours.

The schematic below is of another PAL brand 1 tube amplifier. Though this is a mobile(DC powered) amplifier, everything on the output side of the power transformer should be very similar to yours.

If you can find a schematic for a "Swinger 707" that would probably be the closest to your amplifier. The Swinger is an AC base amplifier with a single 6JE6/6LQ6 tube. Never been able to find a schematic for one myself.

There may be others on this site that have seen an example of this particular amplifier before and may chime in for help.

    Incoming Region Produces X3 Solar Flare

    Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned

    Please advise me to what is a good replacement mic for my SR-497HPC... Answer: 497 is "wired like Cobra", so many choices available. That radio does not need a power mic, so purchase a stock "coffin style" mic with a decent cord, like the ones that Astatic uses. The Superstar DM-507 is my go-to. https://www.ebay.com/itm/3050474478...adANq91JSiEEnz8EGqPJRBloTgEyaVsBoCtoMQAvD_BwE $12.99 + .99 cent shipping.
