Tube Amp Archive

I thought it would be useful for all of the links contributed by folks to date to be compiled into an Excel spreadsheet. The links have been sorted by macro-level to component level; the first category is Circuit Calculators, with the first items being, of course, Ohm's Law calculators, followed by ...

Yes.
There is a wealth of information here you can search for before you start buying parts.

The situation makes me very grateful I thought ahead and bought extra sets of Allen's linecard part number Pacific TW transformers for all 3 models years ago.
However, not sure I need to build any more - have too many now!

DrRogersA,
Use the link in the first post. The spec sheet is linked in the listing for the TW output transformer. Says 7k5.

Trainwreck OT at 7k5?

Definitely higher voltages, but should sound nice. Does it?
Have you played with bumping up the screen voltage a bit, or are you satisfied as-is?
Looks great!

TOM!!!
So wonderful to hear you are on the road to recovery!
And fantastic that you are checking in with us all - you've been missed here, for sure!
My very best thoughts go out to you for your continued recovery and improvement, Tom.

Looking great! Beautiful work. What Heyboer PT did you use? Did you measure power tube plate current and dissipation? If it is high your other voltages will get pulled down. You can adjust your different node voltages by changing the dropping string resistors. Sometimes tube selection will affect vo...

I don't have too much stuff.

My wife will have waaaaay too much crap when I go, however.

Although this may be a general rant about the ban on incandescent bulbs, the common complaint within our community seems to be more centered around dim bulb testers. I recently built a new dim bulb tester/ammeter/voltmeter setup for working on high-power audio gear, using halogen bulbs. I can switch...

Yeah. I got those. Freakin' company said "you've had them 6 months and said nothing, so we can't help you." Never mind I had bought 250 of them and it takes time to use that many. I tried liquid flux to no avail. Even tried a wipe with muriatic acid. Some solder stuck, but it was miserable - they we...

Hi Matoni, First, it's great you are taking an interest in such an arcane activity/hobby (tube amps), particularly as a younger person. It can be difficult to convey information or respond to what is being asked of one if they don't really have a basic understanding of the topic, and electronics (ev...

Would carbon comp resistors work for you? They are rated for high pulse, correct?

Well you now have all of the information you need, now that we all understand what you initially were asking. Forums are a great place to get help, support, ideas, and learn new things. But you also need to be willing to do some reading on your own, particularly when others provide you with valuable...

So you don't want to learn the terminology but you want someone to tell you if it's safe/appropriate.
What's wrong with learning something you need to know? And why push back against people trying to help you?
