Tube Amp Archive

come on guys...I thought that I had finished my penance. I have to say however that I do feel a little proud of myself. Getting a kit that I knew nothing about. Trying to figure out what kind of amp it was. Trying to follow tutorials when I didn't know the difference between an ohm and an amp . And ...

I noticed on this JTM48 that the layout : https://tubeamparchive.com/files/mojotone_jtm45_drawing_186.pdf calls for the Brown wire from the OT be connected to the # 3 pin of the V4 Power tube. AS I'm following the build here: http://acapella.harmony-central.com/showthread.php?2291424-Jtm-45-build-in...

I just broke off a pin to one of my preamp sockets. No doubt from the de-soldering I put it through. I wanna go to Tube Depot for a replacement since they have a STELLAR past with me. Any suggestions? I want to go ahead and replace All the preamp sockets with new. I'm thinkin that the power tube soc...

I think I've decided to build this thing according to Guttermouth's build tutorial. I really have no other option other than having someone do it for me. After much..& I DO mean MUCH deliberation and all the splendid advice from THIS FORUM I feel a lot better mentally to approach this thing. I watch...

Merc,
Just thought I'd share a Champ(ish) Circuit with you....

Now THAT'S INSPIRATION

...Let the questions begin then... My kit obviously has 8 pin power tube sockets. Do KT66 tubes have 8 pins and will they fit the sockets then? Do I need a special tranny for the 34s VS the 66s? Are 66s more suited to a lower wattage amp like say 50 watts or less whereas 34s are usually used for 50 ...

Merc, I desperately want to build this thing as "intended". I have an affection for all things 34 including rectifiers and women. I particularly like the Tone the Marshall 1987 puts out. Short of finding and then PAYING someone to build the rest of this kit for me I guess I'll have to ask several th...

Yes, I noticed LONG AGO those 2 large Caps mounted on the Chassis side....

Merc....I'm ALL FOR IT....can we make sumthin' ?

Dayummmm..how could I miss that Garbage Pail Cap??? Merc, please bear with me...I only bought the 18 Ga. because that's what is spec'd for this Mojotone mystery build. So, If Steve H finds it difficult to work with imagine this Numbskull on his first attempt...usually if it's mechanical I can Deal.....

...I was just perusing all of the layouts you guys were so kind to supply on page 1 of this thread and for the life of me I can't see a 16UF Cap in the approx. position Merc has suggested. I'm on the other side of old so I'll use this as an excuse for not eyeballing it.

I have to redo these horrific heater birds' nests. I bought this stuff online here... http://www.tubedepot.com/tw-18-str.html in black and red. I'm not sure if it's pre-tinned or not but it looks pretty. I have done my due diligence and watched countless heater wiring "tutes" online thanks to you gu...

I populated my board just (I think) just like this board (located on post # 20 this page) which is from a Mojo JTM45 kit like mine. I'm trying to follow this build's instructions but like I said earlier the instructions given are for the experienced builder. It seems that the "Kindness" build shown ...

Merc, I couldn't begin to think about where to put in a 16UF cap. I'm not sure I even know what one is. EL34s , KT66s, tube rectified or not, JTM45 or JTM50, missing turrets then not enough of them. I wanted a Metro with instructions then I was told that this one was a Metro 45 . Then I find out it'...
