problem fixed - i had wired the mains transformer backwards :roll: :oops: i get 6.7VAC at the heaters now, and it seems to have more than enough current reserves to power both pre tubes and the EL34 heaters... am thinking of a way to wire up the power supply without using a board (very little space....

i'm trying to integrate a bax in a custom fuzz - someone i know wants a work-a-like of the neo fuzz.

hope this helps:

progress report... this build has gotten quite far already, pretty much the only thing that is remaining is the power supply, adding a bright switch and standby and wiring up the speaker jacks. now this is what i am rather worried about: i decided to give it a test run after completing the heater an...

wow.... these articles are truly awe-inspiring. i am possibly one of the younger people on this forum (27) and, having spent 19 of my 27 years in india, i have never got to hear a trainwreck in person, and know the sound only from glen's mindblowing music and various clips, which have been more than...

ahhhhhhh ok, i get it now. will do that. thanks for the heads-up! "enclosure" is almost drilled completely, can't wait to get cracking!

hey guys, thanks a lot for the tips. just to clarify - do i need to resize the schematic? didn't think it would pose much of a problem, but i didn't click andtest it myself either :oops: if you think it'll help, i will be glad to redraw. jana, you need to come to mumbai, india to understand what RFI...

...nobody?

thanks in advance.

hope this is the right section... hi to all from bombay, india i've been browsing around these forums for a while. after i recently had some success with an ultralinear EL84 hi-fi tube amplifier, i've decided to roll out another one, this time with an octal output section. the other project i'm work...

there seems to be a fair amount of OEM tube amp manufacturing going on in china - scary part is, i played a couple of them at musikmesse, and they didn't sound too shabby at all. definitey NOT as good as a 2203, a überschall or a wreck... but FAR from bad. i distinctly remember one exhibitor called ...

R for the 6.3v won't tell you much. Five tubes is a decent number. I would assume the heater winding has at least 2A. The exception would be if there was a 6.3v rectifier, in which case, its rating is about 1A more. Jus tdon't look to put in a high mA Octal tube like KT66 or EL34. I doubt it will b...

Phil, thanks a LOT for your patience in writing out that long post! i admit it has gone a bit over my head, but i'm astounded as to how much i learn on these forums. i reallydon't remember the tube complement that well - there were about 5 tubes in the radio, o0ne of them was certainly an ECH81, ECL...

while we're on the topic of unknown PTs (WARNING: NOOB ALARM!) what would be the safest way to determine the current put out by the secondary of an unknown PT? i have this tranny i salvaged from a radio, and would like to do a 2 x 12AX7, 1xEL34 build sometime. dunno if the pT will stand up to it - t...
