Hi   I'm a long time browser but infrequent poster. I want to DIY a tube amp using tubes larger then sub mini. I've already build a Bijou and Maple Tree Ear+ knockoff, both from scratch not kits. Now I need another amp for the 2nd floor of the house. I'd like it to be busier and more...

An LED will work fine on AC. No blink. No need for "AC to DC circuit...." You still need a series resistor to limit current regardless if you feed it AC or DC. Feed it AC from low volt (heater winding) end of a transformer. Don't recommend feeding it AC from line voltage end of transformer...

If you truly have infinite ohms from black to white...the problem is your primary winding is open. You will measure line voltage across that winding when plugged in regardless if the primary is good or bad.

Yes, it sucks to deal with back-orders. Yes, it sucks to pay extra for the privilege too. You can get a part shipped Parcel Post for less than $5, but many vendors don't use them. Then you have the cost of the box. If the part doesn't fit in an envelope and isn't shipped Parcel Post, $5...

Paint is spray enamel from auto parts store. Custom only in that I applied it. The BOM and schematic....give me a day or two to see if I can share.

Finished construction and checkout today. Did some checks of B+ and filament voltage, found them high. then realized they would read high with no tubes thus no load.... Plug in tubes, recheck supplies, plug in cans, plug in source....rewarded with clean sound: rs1smile: Final touches...

Quick pic about 1/2 way wired. Unusual mounts for the caps. Whatcha think? Good, bad, ugly?

It's an Ear+ Purist HD (not 2). The diodes were a challenge. Only 90 percent happy with my solution. Thank goodness it all gets covered by a box :-) Haven't quite figured out how I want to label the panels. I positively don't want to use simple rub-on transfers, not sure I have enough...

Often, blowing the molten solder out works well. Fill the cheeks, heat the solder, and forcefully expel the air directly over the board hole.

It's not my design. Available as both kit and assembled. I just gathered the parts myself. With some documentation help. I only *wish* my decades of experience led me to my own design.

Hello folks. I'm an infrequent poster, but have built electronics from kits and scratch for a few decades. I fell into the antique radio hobby a year and a half ago, so decided my PPA needed some vacuum tube company. I'm putting together a familiar amp from scrach. Since everybody loves...

I will so you will.

Here's a quick shot after paint. Wiring begins tomorrow.

Intend to send a donation to the good Doctor. I'm building this with his blessing, though perhaps I should not have been public.

I'm in the process of building an exact copy right now. Assembled my own collection of identical parts and chassis', don't wanna use the word clon* Chassis is drilled, ready for paint.
