No name Vintage guitar amp

Hi,, thanks for accepting my request to join

Can anyone identify the brand of this amp?

Thanks Tony

Nope. Never seen that one. What is your location, it might be useful context.

Welcome aboard....

I think it's probably a Lectrolab. See the image and info on this page.

A gut shot would also help. What size speaker does it have?

Edit and FWIW: That amp will need some work before it's safe. A grounded AC cable and probably removal of a death cap. I wouldn't use it as is- even if it works. I see it shows the tube compliment right on the faceplate (1- 5Y3, 2- 6SC7 and 2- 6L6) so it's not likely a widow maker amp without a mains transformer. If you can post pictures of the innards, we could make recommendations.

If the cab is cardboard, that would also point to LectroLab...

I worked on one once. Really killer sounding rock noise if played through a sturdy speaker.

The amp schematic is likely SIMILAR to this amp (see below) with some slight variations (tube types, etc.)

Here are some shots of what looks to be the same amp: https://lectrolab.wordpress.com/

Note the post says one of the tubes is a 6SL7 instead of a 6SC7 and I see there is a sticker on your amp indicating the same, so that socket/circuit may have been reconfigured for the 6SL7.

There's the remains of a name written diagonally on the top left but I can't make it out.

Thanks guy’s !!!
When I get some time I will post pics of the internal wiring. It has a 10” speaker that I had professionally re-coned a few years back. the cabinet is all wood. The power transformer went up in smoke last month, so I replaced it and the filter cap can. It lowered the 60hz hum alot, Still would like to lower the hum a bit more.
This amp sounds awesome with a harp, pretty good with guitar. The person that owned it before me had a 10amp fused installed so I replaced it with a 1amp.
Seems to be pretty stable, I left it on for 4 hours under supervision LOL. The wiring is similar to a Fender Champ/Harvard but neither exact.
Thanks again
Tony

Inside wiring

I found a pic of the inside wiring, but the forum won’t let me upload, I exceeded my limit, Is there another way to attach pics?

[J M Fahey]

Worst case upload it to imgbb or imgur or any similar picture site, they will give you a link to image, post it ere.
We can click on it and see it on a new page.
Better than nothing.

Here is a link to the wiring pic,, Thanks JM

I don't know if the 6sl7 or 6sc7 are stock. The 6sc7 has a lot more gain but maybe it was rewired due to 6sl7 being easier to find? Also, if there is no output tube cathode cap, adding one will give it more guts too.

That looks like a tidy job and the inside is a nice surprise, though it looks like the death cap got replaced. I'd want to install a 3-core cable, earth the chassis and eliminate that cap. If it's a regular orange drop it could fail short and connect the mains to the chassis.

Hi Mick
Eliminate what Cap? I am not familiar with the death cap. can you identify it on the pic. I aways thought only Tantalum caps shorted when failed.
Thanks, Tony

Definitely a Lectrolab. There looks to be your exact amp on the homepage of the lectrolab website above. There doesn't seem to be a lot of info on the model though. I bet the website owner would appreciate some of the pictures and maybe an attempt to date the amp using the pot codes
