Bradley appear to have been an east coast company from around the Dundee/Montrose area that existed briefly in the 90s. Their products included hybrid amps and were described as being Marshall/Soldano sounding.
At 9:45, note the little round secondary-supply bridge rectifier inbetween two fuses and a capacitor: best to replace it with a larger, uprated rectifier. Those things are failure-prone even when they're being run within their stated ratings.
The oblong socket is for plugging an old domestic BT phone handle into so you can call a cab to cart the amp home, the player will have to walk...but that amp is solidly built. Reminds me of the early Orange amps( a bit). Can't wait to hear it.
At 4:00 , that's not a Philips screw(s) holding the baffle in place, its a Pozi-drive. Don't use an ordinary Phillips screwdriver on those or you'll likely chew the heck out of the screw heads. There are probably more Pozidrive screws used elsewhere in the amplifier.....[edit: The mounting screws for the PCB also appear to be Pozidrive, which have apparently been chewed up by a previous servicer].
@@giulioluzzardi7632 , they look a little chewed-up already; somebody likely used an ordinary Philips on them. Pozidrive screws are fairly common on anything made in Europe (including IKEA furniture) and, to a lesser extent, Canada.
Vacuum tube pin straighteners are still available, typically between $15 and $30, whether NOS, used, or newly manufactured. Back in the day, every tube caddy and most tube testers had a built-pin straighteener riveted to the unit, or techs screwed one down to the workbench or the wall for easy access, which is why they often have mounting tabs or ears. Be aware that a pin straightener for 12AX7's and other 9-pin tubes actually has 10 holes, and a straightener for 7-pin tubes has 8 holes. A quick look on Amazon and ebay showed that some sellers dont know this, where a 7-pin straightener with eight holes is being sold as an "8 pin tube straightener"; but there is NO pin straightener for octal 8-pin tubes! One new unit I saw will straighten not only 7 and 9 pin tubes, but 9 pin Novar-base audio tubes such as the 7868, 12 pin Compactron tubes, and at least one style of 10-pin tubes (bet many of you didnt know that there are two uncommon styles of 10-pin tubes, one with 10 concentric pins, and another with a 10th pin in the middle, surrounded by the other 9 pins).
PS, for newbies to working with tubes and tube gear, avoid straightening tube pins with needle-nose pliers, as this may crack the glass. If they're badly bent, use your fingernails to straighten them, followed by a pin straightener.
@@BradsGuitarGarage BT Master Socket - came as a 4 way and a 6 way. Introduced 1980 but being replaced slowly by RJ45s. Apparently New Zealand used them too.
Close enough for musician. About 6mm 1/4 inch 12mm about 1/2 inch, 18mm about 3/4 . 25 about 1 inch . Recap for sure for long life. Ribbon on a good day 300volt is pushing it . The connectors are IMHO not rated for the voltage of the plates heater current are ok . Tube pin straighteners are sold by a number of tube sellers. I have a few cinch made ones.
8mm is 5/16", 16mm is 5/8" and 18mm is .71". 13mm is a smidge over 1/2". 19mm is sort of 3/4". MDF is still shit no matter how thick or thin it is. 1/2" plywood is slightly thinner than 1/2". I use a refillable spray can filled with the same thing contact cleaners are made from, mineral spirits AKA odorless paint thinner. No residue.
These amps were not designed for use by guitarists; they were meant to be used with the electric bagpipe and you can clearly hear one in use on Acca-Dacca's 'It's A Long Way To The Top (if you want to Rock 'n Roll)
Mhhh Ardbeg... yummi But... I've never seen such a bad design & construction... :S The relays don't need to be "hermetically sealed", this is mostly for military or aerospace applications. If you look at the datasheet, they are waterproof / sealed. That's pretty much all we want for this kind of stuff. :)
They don't need to be, no. The point I was trying to make is that even the hermetically sealed ones can have issues in my experience. Sometimes from the circuit design, sometimes they have ideal operating conditions, but just start to play up.
👋 hi from Scotland. Never heard of the amp or manufacturer either 🤷♂️. That foot switch connector is the standard telephone plug and socket arrangement used throughout the uk since the early 80s.

I can confirm it does sound a bit like a Soldano.

Nothing says 90's like a faceplate with Comic Sans lettering ...
Dammit! I forgot to make fun of the font!
I did it on my livestream, at least!

Also there are like 6 different typefaces all over this thing! hilariously ugly design!

Yes, I relayed that concern to the customer, too.
😂

I've seen contact cleaners that declare on the can "cleans and lubricates", and elsewhere reads "leaves no residue"!

Well spotted eagle eye...those posidrive screws are made so no-one should be able to get inside and fould things up.

That looks like the RS232 plug in the ZX Spectrum.
Apparently it's referred to as a "BT Plug" for British telephone socket.

What used to be 1/2" plywood is now 29/64ths. (For those who suck at fractions, 1/2" would be 32/64ths).
18 mm = 71" ? I think you've got a typo there.
“Trotter” sounds like Gaelic for hussie.
Diarrhea is sometimes referred to as having "the trots".
It's a British colloquialism for a pig's foot. Some people even eat them.
Interestingly, here we have a Bradley amp being fixed by a guy called Bradley 😀 I just know he is going to deliver a great outcome.
Brad's name is actually *Bradford* if I 'member correctly....
Bradley/Bradford means the same thing, wide water, I know.

That amp belonged to the Proclaimers.

Video poker machine switch.
I have replaced numerous switches similar to that in 1980s and 90s hi-fi equipment.
