Re: TC-50 Guidance

In final play-test we test the amp with all accessories, just as you receive it. That means the footswitch, reverb tank, and in a combo amp - the speaker. In initial play-test we simply use a bench foot controller, bench reverb tank, and same cab for every amp - but in final we test with everything ...

Re: Finally happy with my V

Interesting, as the SPAX7 is exactly the same tube as our 12AX7 - it simply tests for slightly lower background noise and has the wrap to help prevent microphonics.

Re: Mesa Boogie TA15 Metal Cover clean up

Unfortunately, if its got fingerprints and tarnish its probably the result of a previous owner trying to shine it up. The ornaments were clear-coated, and if cleaned with a solvent-based cleaner will eat the clear-coat, and lead to the situation you describe.

You should connect with the MESA distributor in your country for assistance.

The diodes in the LV power supply need to be addressed. This should be done by an Authorized MESA Repair Station.

That is awesome news. Thanks for verifying that. I have a late 73 head that seems to be a prototype. Property tag era. All the ones with the gloss faceplate that I had seen previously were the Japanese clones.
By 73 there wasn't much going on as far as prototypes. Enjoy!

Re: Fake???

That's an early Aidean Zoom copy made in Japan... Also known as a "Meisa". There are alot of em' out there before Mesa got their lawyers mobilzied. They ironically can sound good with a little love... No, this is NOT an Aidean Zoom copy! This is a really old amp that actually predates what became t...

Re: Mark V 90w Midboost

I did this to a Princeton Reverb. In Fender amp with no mids pot you replace the 6.8k resistor on the bass pot with a 100k (or higher) pot. In amps with a 10k or 25k mids pot, just replace it with a 100k pot. From 0-10k it's a regular Fender mids pot. Above 10k it begins to remove the tone stack fr...

My tech (Lowell Amps) recommends pulling the tube as well.
If you did that, the amp would have no sound - V3 and V4 necessary. There is absolutely no need to remove the reverb driver/return tube when using the amp after disconnecting the reverb tank wires.

Re: TC 50 Combo Noise

Hey all, I’m hoping somebody has a similar experience with this so I don’t have to completely disassemble my TC 50 combo amp… The amp makes a noise like tube rattle when I’m playing lower octave notes. It’s a relatively loud noise as I’m playing at about 90 dB and can hear it. At first I thought it...

Re: Replacing Power Tubes in a solo 150w head

Actually by the way things are actually wired in the amp, there is nothing in the power stage that either knows or cares if you arrange your power tubes in symmetrical pairs or not. Let's say your power tubes are three pairs color coded red, green, and blue. One pair of each color. Traditionally yo...
