'69 Marshall PA 20

Post by shaunf »

Hey guys,

Picked up this little guy locally yesterday for the equivalent of about $400.00. Head box is in good condition too, but was covered in some horrid sticky gunk so it is in the process of being cleaned.

Looks like a cool little amp. Tried it for about 10 minutes yesterday just to check it was working. Will give it a proper run on the weekend.

Anyone have any thoughts or experiences to share on these amps?

Yikes! How did I miss this? I like big amps so these were never my thing per se, but they sound really good. Nice one. What was the sticky stuff?

:shock:

:lol: It was just really dirty. I think it's spent a significant part of its life holed away in someone's garage, so it's accumulated dirt and some kind of tacky residue.

Anyway, a bit of rubbing alcohol and some elbow grease and the cab is clean as a whistle.

Supposed to be really clean until cranked. The basic circuit was a PA amp. Several models were tweaked for lead and/or bass guitar (only a oouple of cap values were changed).

If that's a re-issue they were notorious for blowing OTs. Korg USA (Marshall distributor in the US) would replace the OT for units still under warranty, but I think many owners eventually replaced them with MM OTs. I don't think the originals had that problem.

Also very high voltages on the EL84 plates, but I don't recall reading anything about shorter tube life.

So, IIRC, the ...
...PA is Model 1917
...Bass is Model 2019
...Lead & Bass in Model 2061. It was NOT 2061x, the "x" suffix how Marshall designates a reissue.

Also IIRC, their turret-boards were identical and the 2019 and 1917 were the exact same amp with different backplates. The only difference between the 1917/2019 and the 2061 is ONE cap. The 500pf cap on one Tone control is replaced with a 4700pf cap.

Amparchives has some excellent information for the "mini-Me" of the Plexis.

Fantastic!!!!!!

Love the 20 watters. Really underrated amps.

Grissom has done recordings with them for his Book and CD instrucitonal method, and they sound killer.

I used to have the 20 watt L&B RI..the 2061X...and wish I still had it.
Need to build one. Killer amp.

The early rei 2061X amps did have bad transformers, after the 1st year tyhe isolation was changed on the wiring.

Differences between PA and L&B: TWO caps (bright-cap and mixer-cap).

Nice purchase!
