Amp for 80s heavy and hair metal...

Tekbow tells us the Marsha is now the Browneye.

I meant if you have an understanding of electronics and high voltages, you might be able to bias mod the 5150 yourself to decrease cross-over distortion.

Oh yes I noticed that...thx

No my knowledge about electronics is not so high at practical level (I'm still I high school student...) but with a little help from my friends :D :D :D (and especially that electrician friend of mine) I think I'm gonna make it....but I don't know exactly what mods should I do because I don't understand these things in English very much...

Damn you, Tekbow! I'd be so tempted to get my 5150-II modded, but I'm not confident enough to do this myself (pedals, pickups, house mains/lighting, okay, but not then amp...).

Anyone local to the south east region: Oxford/Sutton who would tighten up my 5150-II? :)

 :lol:

Don't worry, im in the club, i'm an engineer by degree, and i understand a little of what they're doing in theory, but i would never attempt it myself. just like i know how a cars engine works in principle doesn't mean i can fix it when it breaks down  :lol:

I'll do it.... 'insert evil cackle'


EDIT: I just read that rig-talk thread. pretty easy mods if your a dab hand with a soldering iron. the hardest on is the bias mod he's done. I bias modded my own 6505 and I actually took the whole main PCB out and inserted the parts through the board. worked fine. The other stuff is real simple.

Is that Sutton as in Surrey or another Sutton closer to Oxford?
If it's the former then we are pretty close - Im only in Croydon and Dmoney isn't far away either in SE London

I'm actuallin in west London now. by White City.
I tend to move almost every year. I hate it. my simple rural mind can't handle city living.

JCM 800 2203/2204 (100watt and 50watt) is a single channel 'high gain' amp. High gain in the early sense of high gain.

the 5150, DSL, SLO, Dual Rec, Splawn Quick Rod, Bogner breed's of High Gain amp all have more gain available and often an added 12AX7. Although not in the splawn case, but it does have an extra gain stage and the expense of another kind of stage. Sovtek Migs have some similarities between Krank amps and Splawns.

Those circuits are born from the trend of modding JCM 800's and such in the 80's. By adding diode clipping or extra gain stages one way or another.

the 800 / SLP is the base point for the amp you want. Not exactly what you're after I think. thats my opinion.

i'm not sure i fully agree, but i know what you mean.

using a booster like an OD-1, or higher output pickups like Dirty Fingers or Rebel Yells gets me that particular kind of 80s tone into a basically unmodded 2204. which is what they did back then too don't forget.

I work in Sutton/Surrey and live in Oxford. White City actually would work pretty well for me, though...

Pop in for a cuppa if time allows sometime Roo if Croydon isnt too much of a drag to get to

[Dmoney]

oddly enough, i just remembered I have to go to Purley today. "Croydon bruv? thats surrey! country-fied bruv!"

[Roobubba]

I've sent PMs to each of you! :)

I played a Jet City 100w head today, £599 out the door - sure I could get one cheaper if I pushed.  Was f*ucking great as it happens, I want one.  Basically a Chinese-made SLO100.

I've gotta say, it sounds good here!
