Re: Dynacord Twen; more???

Hi Bernaduur, do you like the sound of the amp? If you change to fixed bias you'll probably get 2-4 Watts extra at the expense of loosing the original sound. Change electrolytical capacitors and check some speakers. To keep the weight low - it's only 10kg (!) - you could try high efficiency neodyms....

Re: Wreck clean to mean with bleed capacitor on guitar vol?

Hi! Try it for yourself and your rig&playing style. I prefer 50s wiring w. low output humbuckers and no treble cap on volume pot for now. But my guitars are kinda bright and so are my speakers. There is a thread w. some valuable input from Glen Kuykendall and some others a while ago. http://ampgarag...

Re: Trainwreck inspired Amp finished + pics + first recordings

Hi! I've build a 15 W Liverpool (EL84) and like the TT 7025 for V1 a lot. It's a matter of taste though. 5751 might be an option if your not to much into gainy amps. V1 is most important: check for sound, noise floor/microfonic rattles aso. I did check several types for V2/3 but currently use JJECC8...

Re: EL84 Blues Amp

Hi there! Some interesting ideas. I just happen to be on the verge of a new amp with a similar concept. Thought about a 2xEl84 pp circuit w. fixed bias and some special feedback loop. Preamp might be Dumble inspired. There should be two different feedback configurations: 1. 2 gain stages ->PI ->El84...

Re: Bluetone Express Baby ready

Pretty baby, Harry!

Especially like the mahogany and the RED chassis. Did you simply butt joint the boards?

Transformers are looking fat for a <15 W amp. More like 50 W.

Schoen!

Re: Mods for normal channel fender to use with archtop jazz?

Hi sidehatch! I'd reduce the cathode caps. Try 10 uF or 5 uF. Up the cathode resistors a bit. Try 1k8. Use slightly different values for first and second gain stage. Sometimes a cut control in the power amplifier section is nice. Reducing values of coupling caps after stages is also an option. Inser...

Re: 2w Sub Miniature Express

Wayne, it takes an equally warped tube mind to think of that. :twisted:

While dabbling w. my Lil'Wreck I thought a second about it...why not try? Nothing to lose.
