Re: Mesa Dual Rec Roadster Head- Lost Channel 1/2 AGAIN

So here is my update, went to get 12ax7 today at another stores and they only had the SPAX7, which I understood to be better replacements of the 12AX7. So I bought 3 of them and came home. I replaced V1 with brand new 12AX7 V2 Same V3 SPAX7 V4 Same V5 SPAX7 V6 Same Results? Same. Channel 3/4 brittle...

Re: Mesa Dual Rec Roadster Head- Lost Channel 1/2 AGAIN

Thank you both for the reply. I took it apart just now and confirmed Mesa 12AX7 in V 1-6. If the Mesa 12ax7’s say ‘Russian-1’ they are Sovtek, ‘Russian-2’ and they are EH, both are questionable in cathode follower use. The current Mesa 12ax7 will not have ‘Russian’ or ‘Chinese’ stamp on them, those...

Re: Mesa Dual Rec Roadster Head- Lost Channel 1/2 AGAIN

Thank you both for the reply. I took it apart just now and confirmed Mesa 12AX7 in V 1-6. The power tubes are mesa 6L6 GC and the other 2 on the right are not matched (is this an issue?), one is a mesa 5U4GB and the other an ElectroHarmonix made in russia. I have 1 spare 12ax7 here, but feel it may ...

Mesa Dual Rec Roadster Head- Lost Channel 1/2 AGAIN

Hello, another day, another issue with my beloved dual rec roadster 100w head. I use the amp maybe 5 to 10 hours a month at bedroom volume, so not abused at all, but this happens from time to time. Tonight, I was playing a song switching between clean channel and channel 4 and it cut out totally. Ri...

Media Dual Rec Roadster- No Channel 1 and 4 on 50w Mode, etc

Hi all, trying to trouble shoot a weird problem and cannot find anything in my manual or online. My Mesa dual Rec Roadster 100w head had some intermittent problems with channels. In middle of playing of a sudden channel 4 goes out, then channel 1, but 3 and 2 work. bBoth channel 1 and 4 go out when ...

Re: Dual Rec Roadster Channell 3/4 died Suddenly :(

Yup you nailed it here thank you so much, I returned the recto tube today. I replaced both 3 and 4 just because and problem fixed instantly. The last thing I wanted to do was bring the amp in like they suggested, pull and plug tubes was way easier. Finally playing again!

Dual Rec Roadster Channell 3/4 died Suddenly :(

So my saga with this amp continues. The other night I was strumming along low volume with the amp that had not moved since I brought it home and mid chord my channel 3 died went totally mute, no weird noises or anything. I switched over to channel 4, and also nothing. However, channel 1 and 2 are st...

Re: Mesa Dual Roadster Continued Problems- intermittent shut

Just spent another 2 weeks out of town so need to be back on this now. I don't think the fuse has made a difference, and Mesa seemed extremely uninterested in picking up the shipping for this amp, so that is last resort. The only thing I can think of that is easy is switching power cable. When I too...

Re: Mesa Dual Roadster Continued Problems- intermittent shut

I finally swapped the fuse out this evening and after about 30 mins of the mellowest playing session, sitting here reading a tab on the PC, not even strumming the thing, it just shut off completely. And about 3 minutes later, it turned back on. After another 5 mins of the amp just being on and me pl...

Re: Mesa Dual Roadster Continued Problems- intermittent shut

Sorry for the lengthy delay here guys, I was in the US for 9 days for work and am just back this weekend now dealing with music related things. I did talk to mesa the day before I took off and they looked at the video and concluded that there was something in or around the fuse that was likely the c...

Re: Mesa Dual Roadster Continued Problems- intermittent shut

OK- the amp gremlins caught on camera! There are two videos here and I'm pretty sure it is now obvious what I'm dealing with (no 'sound' bar involved :? ) - Today I switched the amp power cable directly to the wall outlet and only kept the pedals in the POWER bar -I played very briefly today for abo...

Re: Mesa Dual Roadster Continued Problems- intermittent shut

I just read what I wrote and should clarify, I meant power bar, not sound bar, sorry about the confusion! (I just recently purchased one so it must have been on my brain). That makes a big difference. The power bar is pretty heavy duty and high quality and I don't suspect this to be a problem. The h...

Re: Mesa Dual Roadster Continued Problems- intermittent shut

Thanks for the discussion here everyone. For background info the amp has never left my house or the outlet it is plugged into through a brand new musician-quality sound bar. The house wiring is 5 years old and the only other thing on that circuit is a Mac computer. I've never had any other electrica...

Mesa Dual Roadster Continued Problems- intermittent shutting

I'm nearly done with this amp, it has been checked over by the local mesa dealer who cannot figure out anything wrong (or will not spend the time to really test it out). It has been turned off for nearly 3 weeks and just now I had it going at 3/10 volume for about 10 mins and all of a sudden it just...

Re: Dual Rectifier Roadster: Possible problem with FX Loop t

Alright so, I got this fixed, hope this post offers some sort of insight for you too Coleo. You mentioned that it came back to life when you connected a cable from the send to the return. I'd already tried that, tone, volume, and dynamics were terrible with a cable in the loop or nothing in the loo...
