Muchless / Stray Cat 30 / Re: Stray Cat 30 - finally finished (1 year later)

Isn't the rectifier board setup to provide the proper B+ voltage to keep the bias within range just like the Bad Cat version? Have you checked the B+ Voltage and Plate Voltages to see if that's the case?
My guess is the design is set up to be a compromise between the two different rectifiers. However, with my particular tranny set, when in Tube Recto mode, I'm running 337.7 B+ (standard JJ GZ34S). When I'm in SS Recto mode I'm running 362.6 B+. My plate voltage jumps accordingly and that is when I'm pushing beyond what I want to in terms of dissipation (I'm fine in tube recto mode). By any chance did you record your readings before buttoning her up? I'd be real interested. I'm going to cool it down a bit so I can use SS mode with peace of mind - I'll report back...have her opened up and the soldering iron warming up.... |

Insane amp...one minor quip, it doesn't seem to like my time- or modulation-based pedals, but I can live with that....anyone else notice that?
Also, I'm curious....for those of you who built your own: I'm at about 24Watts when running with the tube rectifier (with respect to bias).....I'm comfortable with that as I just purchased a new set of Winged Cs to use. But I know (from my previous tube set) that when I kick on the SS rectifier the bias will exceed 100% max dissipation (so I never run her with the SS rectifier). I'm just curious if anyone has increased their cathode resistors accordingly to cool it down a bit when running the SS rectifier and were you happy with the results. There has to be a good compromise somewhere so I'm not so cold in rectifier mode and not so hot in SS mode......

Thanks Gregg!!!
I had an extra day off today and I couldn't stop playing her. What a monster amp....definitely one of those moments where I asked myself why did I wait so long.
I put her in the head shell of my C30 (same chassis in case anyone was wondering - at least the Nov 2010 version was/is). I think I'll put the C30 in a combo cab and keep the Stray Cat in the head shell after all.
Great amp Nik! And great transformers Bob (TDS) - thanks (a year later)!!!

Hi my fellow CF members,
Talk about procrastination. I think I ordered all the parts to build a Stray Cat 30 back in Nov of last year (2010). I even ordered some custom TDS trannies for the build...and, for a bunch of different reasons, the "project" just sat in storage. Well, over this Thanksgiving holiday I got inspired to dust everything off and wire it up finally. Switched it on today and everything works great....what a fantastic circuit!
Now I have to get a cabinet for it...I'm thinking of a combo cab this time (as I have both my C30 and Lightning builds in head cabinets).
Anyways, if anyone needs help with their Stray Cat, C30, or Lightning builds, although I'm no expert by any means, drop me an email and I'll try to help if I can!

Muchless / DC 30 / Re: Looking for an Overdrive/boost pedal for the DC-30?

Fulltone Fulldrive II - Mosfet edition.
The best OD pedal I ever played. I haven't played ALL of them but quite a few.
+1 While I haven't played them all either....the one I find myself coming back to frequently is the FDII (at least for my amps and guitars) and it is one of my favorites in front of the C-30. |

Muchless / DC 30 / Vp, Ik readings on your C-30? Just curious.

Hi everyone,
I am real curious how everyone is running their power tubes in their C-30 circuit?
I'm running two NOS RCA 5V4s and my center tap reads just under 327 volts. I'm also currently running TADs.
I nudged my screen grid voltages down a few volts, but other than that, the rest of my power section is true to the layout (I'm running the stock cathode resistor values). My Ik + Is is right around 38.
What are you guys running in terms of glass and where are you folks at with your measurements - please share? I think it would be interesting to see where we are all at in terms of dissipation results.
P.S. I know I'm a nerd.

Well, I decided to be adventurous and build my own 1X12 cab for my Lightning. Here it is with my HC/30 on top. The cab is birch, mostly prepped and just waiting for the vinyl. Still really enjoying these circuits... sorry the pic is sideways....  |

Just finished my Lightning build using Ceriatone's kit as a foundation and adding some components from Alessandro, Sozo and West Labs. I modded the first stage just a tad (added just a smiggen more low end) and have been really pleased with the results. I also put in a Standby switch and a few other minor tweeks, but, as with my HC-30, this amp is an absolute joy to play! I still got to order a cab from Gabkits for it and as soon as I do, I'll post some pics.
I really like these Matchless circuits once I got into them - sensible layouts, easy to work on, and tone to die for...what more could could you ask for. Great stuff (as usual) from Nik!
