Tube Amp Archive

Thank you very much for the knowledge folks, but it still doesnt answer my question.

I just want to know what are the technical differences (speakers position, measures, etc.) between front and rear loaded speakers.

BTW I guess MM got to the same 200mA on the HT winding the same way I did. It's just simple math. How did you did that? :?: Also... I have a 3.8H 100ohm choke laying around I and was thinking to put it in the dsl401, but the replacing resistor is 470ohms. So the difference would be 370ohms, I figur...

Hi folks!


Whats the technical difference between the front and rear loaded cabinets?

SOLVED

Mercury Magnetics gave me the specs for their DSL401 PT:

0-335V - 200mA

6.7V - 6A

27V - 1.5A


They are a bit strange though... 335 at a borderline 0.2A (marshall says 310V), 27V at 1.5A through a 0.25A fuse!

What do you think about it all, guys?

The winder is a local company and they use only their cores and price them with a standard price. :-S I mean, I asked already for rewinding the old one, they don't wanna do it. They want to make a bigger profit. I have another question though. Will the 6.3V from the transformer be 6.3V in the tube u...

I'm soooo dumb. I can easily take the fuses ratings after the PT as an applicable information. 310V - 300mA fuse 23.6 - 250mA fuse 6.5V - 6.3A fuse For the transformer increasing the ratings a bit would do the job, right? 310V - 350mA 23.6 - 300mA 6.5 - 7A = 161VA Another question, what are the adva...

It has preamp tubes. The problem is that I dont know the ampere rating, the states above are just guessings. :-/

Hello! First of all, great forum. :) I've got a problem and maybe someone here can help me. My DSL401 blew up (fried) the power transformer, and I dont want to buy the same from Marshall since I think it's an accident waiting to happen. The mercury magnetics is way out of my price range, and I'd hav...
