Re: my 18 watt rocket-ish build
thanks. in that case I think I built a very functional, but very boring sounding amp.martin manning wrote: ↑Wed Apr 10, 2024 4:20 pm OT secondary has one end grounded and has very low resistance, heater winding is also very low resistance and has a grounded center tap, so yes.

Re: my 18 watt rocket-ish build
this might be a stupid question, but with everything unplugged should my heaters and output jack have continuity with ground?

Re: my 18 watt rocket-ish build
how much does the primary impedance of the OT matter. im wondering if that might be my main problem.

Re: my 18 watt rocket-ish build
bumping my own ancient thread. I built this amp. it looks good. it sounds ok-ish. nothing great. I built this before there was a z-wreck jr. and based it off of what I believed to be well researched info. so now I'd like to finish it and get it sounding good. going off of the c-wreck CeriaTone layou...

I was considering making it a 1 or 2u rack. but I came across the peace hill preamps. it has 2 tubes and a full layout l...

Re: am I ready to build a dumble style amp?
Going back onto this thread. Trying to research some more to get closer to what I am looking for.
Anyone have a clue which of the schematics and layouts online get closest to this?

Re: Anyone in NJ area test tubes. Mostly non guitar amp related
good call. you are the second person to suggest that.
it's probably what ill do. ill take out the few 12ax7s and stuff and maybe just donate the rest. im not looking to make money or deal with possible suspect 90 year old tubes. some of these have 1940s dates on them.

Anyone in NJ area test tubes. Mostly non guitar amp related
Bought this years ago at some online auction. Never did anything with it. I don’t know what most are. Just looking to determine if they are garbage or worth finding a home.

Re: 2nd Generation 50w Period Correct ODS
im not familiar with bumble terminology or any of that, but ive always liked the clips ive heard of the 2nd and 3rd gen dumbles Ive heard clips of. (I believe Mayer has one out on his solo tour, and Santana used one for a while). trying to compare these early layouts to something like 124 and later ...

50watt ODS power amp only
has anyone built one? I have a few preamps I currently use into a power station that id prefer to go into a 50w el34 combo with a built in power amp instead. looking for advice on people that have done something similar. how would building a dumblelator into it change things. https://www.youtube.com...

Re: Dumble Style ODS Project Chassis + Boards - Black and Silver! IN STOCK
Have you ever considered doing a build class like egnster does. Probably not worth it for the time it would take to organize it but I’d love to complete one of these with someone standing over my shoulder
