Up until this point i have never pulled the baffle on this original 18w bluesbreaker so drum roll...
Its the money shot!
Also a great way to verify any original marshall head box or cab.

My friend just reminded me...
Yeah,
It most certainly is a reality check...
I had completely forgotten that was a 20w spec transformer and does not include the 5v tap for the rectifier.
It is absolutely not the correct transformer but the amp works great! (they just jumped the heaters off the other tubes).
I asked john at the amp shop if there is any danger in doing that?
He said it is supposed to be 5v and two 3v=6v so being 1v of could slightly shorten the life of the rectifier.
You know I run this amp on 115v (or 230v) to maximize the safety and life of everything in the amp.
Thanks for responding!

The power supply transformer is a 20w specification transformer and does not include the 5v tap for the rectifier.
It is absolutely not the correct 18w specification transformer. However it still is original to the amp and of course the amp works great! (they just jumped the heaters off the other tubes).
This was the transitional time at marshall, when they were going from tube rectifiers to diode rectifiers.
So here is a weird one!
Changing transformer manufacturers.....
This goes back to reducing company cost.
And the way people understood how to build amplifiers.

I'll spell it out for you. This, among many other things, CONFIRMS your amp is not an 18 Watt Marshall. It's probably a later, much less valuable and less collectible 20w combo with a large number of replaced parts to convert it - unsuccessfully as it turns out - to an 18 Watter to con someone into paying 18 watt money for it.

And yet not only do you ignore all the feedback from people who have legitimate examples and know what they're talking about, you're trying to sell it for $30k?

Please quit with your delusional nonsense.

I've never heard of a real one going for £30k far less a knock off.........
I remember owning a 1930 popular that had been tinkered to 1958 spec, still wasn't an 18w no matter what.

I recently sold a very early 18w with corner logo, grey RS caps, block logo footswitch for $30k. The buyer just had to have it. It was a solid, straight amp and the buyer is an extremely wealthy man.

Now that's impressive. I've got a guy offering a 65 ES335 for mine......probably best keeping the Marshall. 8)

Indeed, but it was among the very first built. Neil sorted it with some NOS caps and it sounded wonderful. All else was straight, it even had the original cover. A very, very rare piece. I told the guy he was paying double market price, but that's what it would take to buy the amp. It wasn't really for sale. He jumped on it. I miss it.

Hello All,
I'm new to the forum and I'm looking to get some help on verifying 2 Marshall 18w.
One is a 1973 model 2x10 at 240v and the second is a 1973 model 2x10 at 120v.
I've owned them for 17yrs. Recently sold them. And of course now all the experts have chimed in, so the new owner is in doubt.
From reading threw this forum, it looks like Banker is knowledgeable with 18w ?
Any help contacting Banker or someone else with solid experience would be greatly appreciated.

:cheers:
