| Hey, all. I have an opportunity to buy a Vegas 400 locally for $150. It's a little banged up, but everything seems to work. I suspect the price reflects the cosmetic condition, but are there any standard issues that I should be on the lookout for? |

As long as everything works, get it.
Its only real drawback is the weight. Sometimes they get noisy, but that's fixable. And at that price you can't go wrong

The Vegas is the same amp schematically as a N-400 with a second channel voiced for guitar (passive E.Q. controls on that channel).
After servicing around 300 or more of these amps I see the same issues that need attention:
-check that input jack contacts are clean and allow the input to be grounded when no instrument is plugged in, if not the amp will have noise issues until an instrument is plugged into it
-check and clean the loop return jacks on the front and rear of the amp. The one on the rear is the worst for having a high resistance on the contacts, thus disconnecting or partially disconnecting the pre-amp from the power amp.
-The pots that often need cleaning are the reverb, post gain and the mid pot (this one can cause the amp to occasionally emit a sound like a 38 pistol going off near your ear, at the full 200 watts RMS).
-re-tension the female pins on the Molex connector for the reverb tank connection near the chassis.
-re-tension the Molex speaker connector female pin (later models had the speaker cable soldered in place, as it was such a maintenance issue).
-Speakers on the older amps often have an issue with the foam rubber dust filter in the magnet rotting out. That can lead to speaker failure. If you can see light thru the screen, then it is rotted or nearly rotted out. There have been numerous posts on that here, so no need to go into detail over that.
-Older 3 spring reverb tanks have a foam piece glued to the inside of the tank, just above the springs. This foam eventually rots and deposits a gummy black substance to the springs, ruining the reverb tank sound. Not repairable, tried to clean the springs and it never fixed the tanks. Suggest a new MOD tank from Antique Electronics, 9EB2C1B. I have used close to a 100 of these tanks and prefer them to anything else I have tried.
-If your 3 cord plug ground has been removed then have a new cord cap installed!

black brass screw (small blade opening)
white silver screw (large blade opening)
green green screw (ground hole at plug front) |
