I would buy a used Fender Blues Junior, do some of the BillM mods, maybe put in a Celestion speaker and I think you'll be happy. This little amp screams if you crank it, and it has just the right volume for club gigs. A good overdrive pedal in front and you play singin and screamin' leads.
I...
That's true, you definitly should know, that the amp was used regulary. Sorry 'bout my joking...If it rested on a shelf or in some livingroom collection for a longer time, you should at least power it up slowly with a variac.
(Anyway I wouldnt use a vintage amp for touring.)
I have a BF...
Looks good, for what I can see everything original. Looks quite like my 73 Super Lead. price is quite high. Did you buy it already?
BTW: the only thing I would be afraid of, is playin with that old two prong chords. Thats really DANGEROUS. Filter caps last much longer, than many people like to...
I wouldn't change anything, if the amp runs without hum. I have a BF Deluxe Reverb from 63, dead stock with original Caps and it works flawless and sounds great. If an amp ist played constantly, this caps can last quite long. What makes them bad, is when the amps stays unused for a longer...
I owned a 6100 which had the same problem after I bought it on ebay and the seller didn' pack it in a proper way. that thing must be crashed on the floor or something. The tech which repaired it, told me that the oscilator crystal was broken. After putting in a new one it worked properly.
Maybe...
35W is MAXIMUM! You should never bias at maximum power dissipation, exept you want to extra sponsor the russian or chinese tube industrie and you have some extra money for a new amp or a new power tranny! 70% of the maximum, which is 24,5 W should be the highest!
Hi Punk
as you noticed: when you run the tubes to cold, you loose power. If you really want to go for optimum power you need an oscilloscope and a frequency generator and so on...
the socket probes often have a 1 Ohm resistance between ground and cathode because its easier to mesasure...
Also IMHO: if you want to make your Marshall sound "british" eg. like a Marshall should, change to EL 34.
It's a huge difference: they breakup earlier and have a lot more midrange and overall distortion. KT 88 are very strong, loud and clean. The 6550 is a cheaper KT 88 which does not take that...
35 w is the maximum the 6550 can dissipate. If you bias your Amp that high your tubes will wear out quite fast and the sound does not get better. you should bias between 50-70% of the maximum dissipation.
4-5mA difference is acceptable, some people even say a little mismatch sounds better...
That's a hard question, which is the best Marshall ever. I think actually there are very few Marshalls that are bad sounding.
My greatest sounding Marshall is a JMP 73' PTP 100 Super Lead, on which I clipped out the 5000pF treble cap to stop my ears bleeding. Now I can use cleaner sounds also...
Hi guys.
I recently bought a red 1960A JCM 800 Cab. On the plate with the serial number it says 260W, which made me think it's loaded with G12T-65. Also the Doyle Marshall book says there exists a 1960A with G12T-65. When I opened the Cab, at first I was dissapointed: it was loaded with 75s...
