Re: Who is making good quality current production EL34's?
Just skimmed your latest comments but if the tubes are not oscillating, don't worry about it. All tubes are microphonic to a point and will make noise if you tap on them. The question is whether they are so bad that they start squealing on their own due to the normal vibrations of playing. I agree w...

Re: Who is making good quality current production EL34's?
I blew up an expensive set of SED Winged-C's F-ing around with the bias. Set the bias cold, as cold as it still sounds good, and leave it alone. IME there's not much to be gained tonewise with hot bias in a Marshall type of amp. A Vox AC30 maybe, but not an EL34 amp. IME EL34's sound good over a pre...

Re: Who is making good quality current production EL34's?
SED Winged-C's are nice, but expensive.
I'm using JJ E34L's now in my Marshall and Marshall-alike. They sound good in a heavy sounding amp, nice bass and like most JJs they are a little dark, which can keep it smooth sounding.

Re: VOX AC15 project?
Hammond makes replacement transformers and chokes for Marshall, Vox, and Fender that are reasonably priced, too. I got one of their Marshall replacement transformers and I am happy with it. Check them out if you need a power transformer or etc that is spec'ed for a Vox. Edit: Also, mojotone is a goo...

Re: VOX AC15 project?
The "problematic-ness" of the EF86 was because they built the amp as a combo and it was picking up vibration from the speaker, making it oscillate. Build it as a head, and if you have problems don't put the head on the speaker cabinet. I built a 10W version of an AC15 as a head and have ne...

Re: Diaz Amps
Right, overdrive/distortion is overrated. "Response" is where it's at. Few get to experience that because it requires a lot of db's and SPL's.

Re: Diaz Amps
Re. using a pedal- I plugged my vibe in between the guitar and this filter and it worked just fine. More treble emphasis as expected. To really do this to get "the sound" there's no need to use an overdrive pedal or fuzz etc. Crank the amp and get the output stage compressing and you get a...

IMO the stock tone circuit was useless, YMMV. It's still kind of a cheez-whiz fuzz IMO but something for the man who has everything I s'pose.

I put a switch on mine to turn off the octave so it makes a nice fuzz too.

Re: Bass flubbyness in a Ceriatone DC30
Yeah, I don't have a "normal" channel on my little 4W amp. But I have tried that rangemaster -> normal channel thing on an AC30 and it does sound good. That's how he got a smooth compressed high gain sound. The top boost preamp is set up more for the typical "vox jangle" sound. T...

I've got far better results by backing off those big 1 meg grid R's in these EL84 power sections. Those are 220k according to the layout he posted.

Re: Bass flubbyness in a Ceriatone DC30
Good advice, Bajaman. Talk to the guy who sold it to you first. Another possibility would be adding a choke if it doesn't have one. But like nfb, that will affect feel as well. These are simple amps, you only have so many cards to play with, and everything affects everything.

Re: Bass flubbyness in a Ceriatone DC30
Is this the one with the ef86 preamp and rotary switch for selecting different coupling cap values between preamp and power amp? I built an AC15 like amp with ef86 pre and 6bm8 power tubes. I had to reduce the value of that coupling cap quite a bit to not flub out with humbuckers. It has a 3 positio...

Re: Marshall Artist Demo Vid
Thanks for comments!;-) It's a nice sounding amp. I got it from craigslist for $125, since it was kind of halfway diy-ed already. The heads go in the $400 range on ebay and etc. There are a lot of features for the price and it really does sound good, esp with some minor tweaking. Hoping to install t...
