The Amp Garage

ah well - back to the dogs dinner - thanks for looking anyway.

thanks geezer much appreciated - hope he doesnt mind me using pictures of his [pristine looking ] amp

my pre amp board looks like a dogs dinner with all the changes I,ve made - i remember seeing this photo of a board with spring clips in place to try out different value components without messing up soldering and thought what a great idea - anybody know what are they called and where you get them fr...

just to let anybody know who might have had the same problem - it WAS the wiring on the relay ! I wasnt aware but the HRM is slightly differently wired than the non-HRM - the former has completely seperate clean/od master vols and the latter has the master vol as a master volume for BOTH channels. T...

thanks for replys lads - yes I have the usual 250kA OD gain pot and 1MA for both the clean and OD masters and I didnt want to fiddle with the trimmer anymore coz I really like the gain set up as it is - but your'e right it is set very low - I,ll just have to put it up then sort out the gain on the f...

sorry-havnt explained it very well - the amp works and sounds great,the only thing I have a problem with is that when you do a gig [as you explained in previous post] you set up the master volume relative to the gain you want from the pre amp and the OD master [or ratio] vol,but when things get a bi...

thats what I want from my amp aswell ! but because the lead master is flat out and still not as loud as the clean then I have to resort to turning up the master volume to try and get more out of the lead channel which in turn puts the clean channel up.A simpler way of putting it would be - how do I ...

sorry-just checked - the od does go via the master vol so when I,ve got the lead vol flat out and its stil not as loud as the clean channel - I have to turn up the master and thats where my problem is !
any suggestions please ?

following 101 schematic and youre right - they should be independant and theyre not so I,ve wired switch up wrong - thanks for help !

hi just built HRM type amp that sounds great but at the last couple of gigs I,ve used it at - I have the OD volume flat out and its still not as loud as the clean sound which means I have to turn up the master volume to compensate which means the clean channel becomes too loud.Amp voltages all check...

aha ! gawd bless ya guv , will start on sorting out the chassis tommorow - is it worth just changing OT first and seeing the difference ? or just go the whole hog and change both ?
gratefully relieved ,

could I use the trannys from 50 watt carlsbro 50 top amp ?

with two 6v6's ?
hopefully, yet resigned to dissapointment,

thanks for all the suggestions lads ! I,ve already tried the bypass 4.7uf cap and .02 CL2 coupler but still the same - its actually not that bad a sound but not quite what I,m after. I,ve got a couple of OT,s knocking around from some different english amps - going to see if any of these will work. ...

just tried adding other 470r on choke and already have bass pot lugs connected and the presence [not going to ground] i have switching in with 390 r on a relay when the od is engaged and nothing when the clean channel is on. Still the same ! I,ve also just double checked all voltages which seem to b...

just tried that thanks and it makes it much better putting the dlite pre thro 124 power which must mean its something in the dlite power stage. I,ve used the usual 4 x 47uf with 2k2,22k and 2k2 between them and 2x 100uf caps with 220k between them with a 470r as choke so what do you think might be c...
