Re: what do you guys think of this?? (guitar player article)

i remember asking you R.G, 8 or 10 years ago about saturation, and gave me some nice explanation. That's why i brought this after reading it. And the conjuctive filter formula states that the resistor should be something like 1.3 times the impedance of the primary. So an 8k primary for 2xel84s will ...

Re: chewy notes on D-style amps

Re: new chinese laney lc30112

i'm a big fun of laney amps. the lionheart ar amazing. as are the gh. even this chinese lc doesn't sound bad at all. they have toroidal pt, and are built really good. my point is that they changed a good design. why not building the same amp in china....??

new chinese laney lc30112

hi. i just opened an lc30112 chinese made laney. the manual states that it's got a different circuit from the english made one. so i was curious. it's got a three stages clean channel, which means that it's extremely easy to overdrive it, and not so much clean gain on tap with hb. the distortion cha...

need old teisco amp schem or info

i have a teisco vt cabinet one, model c-1, for repair. it's tube compliment is: 1x12au7; 3x12ax7; 2xel34. fixed bias, choke, and two small transformers apparently for reverb. i got it with a few blown components, so don't know actual values. any ideas where to get a schem? thanks in advance.
