She's a slippery slope.... now you're hooked on amp building as well...


I have been told about some self help groups that might get you off it. I never go there though.... ;)

Well if I end up electrocuting myself, I won't need to worry about it.
 
You mean "Fired right up" like in this... ???

Nice one, I bet you're stoked! Now what amp next....? ;)
 
If you're after this looking for another project I really like the Matchless Lightning whc you find a layout on the Ceriatone website or the Ceriatone 'Creme Brulee' which is a take on Matchless Nighthawk with Mastervolume. Both are hefty loud 18 watts or so too, two EL84s in power section.
Ceriatone unfortunately doesn't post schematics only layouts, however they also have typical voltages for builds posted or you can get them on request which is quite useful to check completed build. I built both of those from scratch and not from their kits, got parts mostly from antiqueelectronics / tubesandmore

and transformers from classic transformers

Is it the Creme Brulee lunchbox you are talking about?

Yes basically. I built it with a few little variations, but nothing major. Sounds great to has a lot of voxy feel to it and can grind too. I like it mainly on the cleanish with a little hair settings as I get my dirt from pedals.
 
Both the Lightning and the Creme Brulee/Nighthawk will sound different to your single ended beefed up 5F1.
Push pull with mastervolume, EL84 and the Creme Brulee has also the EF86 input section, quite some differences to the first build you did.
 
I had & tried a Hot Rodded Vox AC 30 type and Tone being Bass & Treble with the Hi Cut, It was too Chimey (Bright) for me & I couldn't dial it out.
Even through a 4 X 12 Cabinet.
I think if you like the Fender type tones, you may not like it.
If you are looking for a tonally Brighter Amp, it may work for you.
 
Congrats on the amp build C.M ! Awesome !

Im almost there....still doing research , watching amp building vids, I want a 50W modded 800...

SWEET! Did you make the cabinet too? Where did you get the transformers? Did you go full vintage and use an ungrounded power cord? ☠

I got it as a kit from BYOC, they supplied the transformers as well. I am getting some crackling hum after about 10 minutes, so I am thinking one of the tubes my be a little flaky but it sounds great otherwise.
 
Check all of your solder joints. When the temperature rises, things move around. Make sure the tube pins are clean and the sockets are tight. Retorque any screws that have solder lugs on them. That 25uF electrolytic up against the 470Ω heater is another possibility.
