My Monster w-d-w, multi-amp Rig

feeds@yuku.com (Zachman) — Sun, 25 Oct 2009 22:07:45 GMT

Hi guys... LONG time Boogie user here. I got my 1st Boogie, a MKIIB combo and matching 1x12 cab-- back in '81 I think. Currently I own and gig regularly-- a MKIII Coliseum Simul-Class Head (One of approximately 200 made). I'm the original owner and bought the amp new in 1986 from Lab Sound in LA, CA. This amp has been my main work horse amp for the last 20+ years. I LOVE it!!!! I also own a MKIII Simul-Class combo (Blue stripe), and a few 1x12 Boogie cabs, Rectifiers (mainly rentals)....

Dual Caliber DC-3 volume issue problem

feeds@yuku.com (jbbdabear) — Sun, 25 Oct 2009 17:49:36 GMT

My DC-3 is having volume problems. All 3 channels work at low volumes with the output level knob at 2 1/2 or under. Once the output level knob gets up over 3 the volume drops to about half . The volume sometimes jumps for a split second but then drops back down. I had the amp bench tested at local store and was told all tubes were fine and they could not diagnose problem. Has anybody heard of this problem or have any suggestions?

Thanks

Nomad 45 / 55

I am looking at a used Nomad 45 & 55. This will be my first tube amp, and I really don't know what to look for to make sure they are in good working order. Any tips? Also, I've done a google search for reviews and found that many people bring up reliability problems (tubes burning out quickly, etc). What are your experiences with these models?

Also, what are the differences between these two models other than the wattage?

Thanks for any help!

Dual Rec Roadster Volume question

feeds@yuku.com (fullreleaseblake) — Tue, 22 Sep 2009 07:11:18 GMT

I just recently recieved a Dual Rec Roadster, and had some questions about the volume control on it. I've always heard that with tube amplifiers, they sound their best when the volume is 3/4 - maximum strength. With this head, each channel has its own master volume, as well as a single "master" output control (active when using the effects loop). So, as I can't have both the master volume for each channel and the main output volume maxed out, because it is to loud for a...

power tube configuration

feeds@yuku.com (JimmyJam) — Mon, 21 Sep 2009 08:39:22 GMT

Hello everyone, I recently acquired a Mark V head and wanted to experiment with different power tube options. But I'm unsure about one thing.
The Boogie site says that I can run EL34's where the two outside tubes are located, with the 6L6's still in the middle. how do i set the bias select switch in that case? Or is that only for a certain power wattage setting? it'd be cool if i could run some of the channels with the EL34's and some with the 6L6, but if it's...

Weird channel problem

feeds@yuku.com (madastrota) — Sun, 23 Aug 2009 11:38:34 GMT

I've got a Nomad 100 3-channel head. For some reason, when I turn it on all three channels engage at once which results in a disturbing buzzing sound from the head. I assume this is the problem because when I plug in the footswitch, all three channel lights are on and as soon as I press a switch for any one of the channels, then that channel is engaged and the buzzing stops and everything works fine - almost. When the amp has been on for a long time, even in standby, a vague burning...

Power tube filament clamping resistors Boogie 400+

feeds@yuku.com (doctorcorey) — Sat, 15 Aug 2009 11:58:12 GMT

I need a bit of help from a Boogie tech. I had a tube socket fry on my boogie 400+ due to some past repair and improper routing of some wiring. There were two resistors, presumably, that were added, one each, to the hi and lo filament rail, attached to ground to clamp the filament voltage. I believe these resistors were originally installed on the board in positions "r311", and "r312". Can someone tell me the value of these resistors? I have found the resistors in a...

M-Pulse Noise Problems

feeds@yuku.com (bassman5s) — Sun, 09 Aug 2009 16:14:48 GMT

Hello, I am new to the group and have a M-Pulse 600. At last night's gig I heard strange noises coming from speaker cabinets off/on. Kind of like a laser gun or pulse ray. I have owned this amp for a few years now and have not heard this noise before. I am using a Carvin 2x10 (4 ohm/400 watt) and a Carvin RL-15 (4 ohm/500 watt) speaker setup. I reversed speaker cables, changed bass guitar cable and flipped "on" the ground lift switch (which I don't think had anything...

Blown fuses

feeds@yuku.com (chrislasais) — Tue, 28 Jul 2009 12:45:52 GMT

My amp had been blowing fuses so i changed the power tubes and it still blew the fuse. Any ideas on what might be causing this? Thanks.

20/20 Ground Issue

feeds@yuku.com (ronstephens) — Fri, 24 Jul 2009 14:01:55 GMT

There's a ground issue between my Mesa 20/20 and my Randall RM4 resulting in LOUD 60Hz hum. I've swapped every cable (except the 20/20 power cable, which is hardwired), verified clean AC, etc. etc. yada yada yada.

The only way I can resolve the issue is to lift the AC ground on one of the devices. It would appear that one grounds the signal to it's chassis/AC ground, while the other isolates the signal from the AC/chassis ground. (That's my best guess. I've seen...

Help spilt coke in my rectifier!

feeds@yuku.com (steeldragon mark) — Tue, 16 Jun 2009 00:59:45 GMT

I've been playing guitar for 22 years and never damaged a piece of gear.
Until now!!
I spilt coke down the back of my dual rectifier, about 2/3 of a glass. The boogie fizzled then popped and died (with some smoke or steam - not sure which - coming out of it).
( Luckily I managed to keep my guitar out of the way!)

I drained it out and mopped up what I could then left it to dry out.

The amp is insured and...

(LOW VOLUME) mesa boggie single rectifier rect-o-verb 50

feeds@yuku.com (goulasos) — Thu, 04 Jun 2009 05:21:10 GMT

Kind of a noobie question. But this last weekend I turned on my amp and went through the normal process of warming up as I checked the tuning of my guitar. I noticed however the volume was barely recognizable but does raise slightly when I turn the amp up another quarter way. I have always played this amp at 1/4 of the way and it is roughly 2 years old. Also, I receive the same action on both channels and I can not figure out the reason why.

I did notice on the 2nd channel...

Irregular sounds from amp.

feeds@yuku.com (CharlesSpencer1981) — Sun, 31 May 2009 11:27:54 GMT

I bought a Nomad 55 two days ago. I think its a good amp for its price. But, my reverb is not working on any channel so I know for sure thats a problem. But also, on my channels 2 and 3, there is this constant hum, kinda of like a spotty noise when your not playing. Is that from worn tubes? I really need to find a dealer or someone who does maintanence in my area. I live in South West Georgia. Wonder what the costs will be to have this amp serviced? Mesa is never opened on weekends....

I am new and I have alot of questions regarding Mesa.

feeds@yuku.com (CharlesSpencer1981) — Sat, 30 May 2009 08:21:56 GMT

I just purchased my first tube amp yesterday. I have been wanting one for years. It's a smaller amp thats no longer in production at mesa however, it is a mesa so I rolled the dice on name brand and brought home a Nomad 55. This is the worst sounding amp I have ever heard in my life. The reverb does not work. There are three knobs on the back for each channel and a place on the foot switch but none of that works. Horrible humming on channel two. There is no depth in its tone and it comes...
