Hi all, I've harassed you all over the years with my tiresome questions but here's one more for the pros: The BA manual says to take the speaker down one jack when using only 6V6s. Now I use the 6V6 setting exclusively and I have a 4 ohm load (currently plugged into the 4 ohm jack). What...

Hi all, I own 2 Blue Angel combos. They don't sound identical and I started to investigate why. I got a warmer, richer sound sound with better breakup in the older amp. Now I realize they don't have the exact same tubes, but my idea was to adjust the trim pot which according to the schematic...

Hi guys, I would really like someone to set me straight on the output transformer for my BA's. The Manual simply states that 6V6 setting should be run on the 4-ohm jack(s). Is this assuming that the speaker load is 8 ohms? This goes against everything I always understood about impedance...

So I had this annoying problem last year and replaced all the tubes and filter caps (expensive!) to get to the bottom of it. It worked fine until recently. What I notice is that the volume drops about 10-15 minutes into playing (sometimes more). The odd thing is that flipping the standby...

I had a problem with my BA, volume was fading in & out. Took it to a tech who only found a burnt resistor and changed a diode (?). Then a few days later, the problem persisted and the amp stopped making sound. So I tried variou stube swaps, rectifier and power tubes, didn't help. I suspected the...

Ya it's my blue angel acting up again. I remember reading once what at causes that sound but can't remember now. It's the ticking, glitchy sound very much like an old modem. It's intermittent and sometimes quite loud. Happens even if I roll the volume all the way off, but goes away when I...

Hey all, I think my Blue Angel may need to be re-capped. I'm not sure of course but the amp is roughly 20 years old and it started having problems (read below for a description). What bothers me is the cost of Atom caps! Why, oh why do these things cost $15-20 and availability of 30 uF is so...

I'm sure there's a simple answer, but I haven't found it yet! I can't seem to locate the d-shaft pots that my BAY uses. Only tube amp doctor seems to sell them and they're in Germany. Would rather order in North America... Thanks!

Hey guys, My Heartbreaker has started doing this random static/popping sound as if someone were playing with the input jack. I'm guessing a loose connection/solder joint? How should I go about isolating the problem and solving it? I can't play the amp when it's doing this.

Hey guys, I feel a bit dumb but I can't can't figure this out: I want to run my 1x12 BA combo + a 2x10 extension cab. Right now my 12" speaker is 16 ohms and the manual says to use the lower impedance jack when using 6V6's (which I use most of the time), so it gets plugged into the 8 ohm...

Why am I such a twit? I know you can't answer that, the question was really meant for me. I kept on hearing all these rave reviews about the Blue Angels' breakup character but never experienced it for myself. Why? Because I never crank my amp. Why not? I guess because I tend to think in...

Hey all, I have a Blue Angel and a (modified) Heartbreaker. On each of them, I sometimes get unexpected volume spikes. I have noticed that the volume/gain pots are very scratchy and the volume jumps when I turn them. Can pots just die like that? Granted the amps could be nearly 20 years old...

Hey all, I had the crazy idea of re-housing my 1x12 Blue Angel into a pine head + cab to save some weight. Then I thought hey, what if I actually re-house the circuit with chassis-mounted tube sockets etc? Has anybody done this? OR alternately hand-wire (clone) their Mesa?

I guess I might as well show off my amp. I don't have many hours on it yet and I haven't been able to crank it, but that's life with 3 young kids. Background note: I have wanted this amp for about 15 years! It was WAY overpriced when new, and living in Montreal, Canada they just don't show up...

Hi all, I have a nice Blue Angel which sounds great. However, I suspect a grounding issue because when I touch the metal parts like chassis or chassis mounting screws, I get a reduction in hum. I first noticed when I touched the barrel of my patch cord (at the guitar's jack) and figured it must...

Hi all, my Blue Angel has the chassis screws passing through these nice chrome washers instead of chassis straps, like on the Lonestar. They're pretty flat to the surface and look classy. I wanted to know if they can be bought anywhere online? For some reason, I can't find a decent pic on the...

Sometimes I really wish I could use headphones for playing at night on my Blue Angel. Can headphones somehow be used in the slave out?

Hi all, I was just wondering what would happen if you take the fan out of a Mesa which uses one (like Blue Angel)? Thanks!

I got a Heartbreaker combo recently and UPS graciously broke the cab in transit along with 2 preamp tubes and a hole in one speaker cone. So lucky me, I get to restore it. I'm not as pissed as you might think because I have been wanting to attempt this for some time. The PITA is having to put...

I grabbed a HB for a good price on ebay and have been reading up. I'm excited because I have wanted one for many years! A few questions: -Is a speaker swap in order? I didn't like the MC90 in my Blue Angel at all. -Can it take KT66 tubes if I remove the retainer clips? -Has anybody done good...
