So when I bought my new 5150 least year off craigslist I asked the guy who sold it what kind of tubes were in it. He told me JJ's and I could see JJ's in the power section and was happy with the answer.
Over the last year I have listened to a billion and one 5150 clips and always wondered why mine sounded different. Everyone has always said they really enjoy my 5150 tones and that they seem smoother then others. I attributed it to the age of my Mesa Cab and getting really lucky on mic position.
Well Thursday night at a show I blew one of the internal fuses, so I opened up the chassis for the first time and noticed something.....
Classic fucking NOS Ei Tubes in the preamp, so I did some research and found out these fuckers are super rare, and they are similar to a JJ but more smooth in the top end. 6 months ago just to have as backups I bought a set of JJ's and put them in just to see if I could hear the difference and OMG the highs are so fucking harsh ...lol
Well I finally found the reason this amp sounds so fucking amazing, and I am extremely happy, so the JJ's are up for sale as I am buying a quad of these Ei tubes as a backup off ebay.
This is what happens when you just take someones word for it and don't bother to check yourself. Luckily this time it worked out in my favor. I swear if this amp gets any more mojo from something I am gonna freak ...lol
Ok so to all you tube amp Gurus, does it look like any mods were made? Figured I would snap some shots while the chassis was open and ask:
