Ken sent me more pictures. It would be interesting as the production is entering the final stage. I will not write much about this transformer as I have done that in my first post here. Feel free to check the...

I have spent quite a lot of time to find a good transformer maker who can build something “beyond ordinary”. That means something standard (or a bit above standard) is no longer interest me. I spend hundreds of emails to...

This is just another simple shoot. I don’t know why, the appearance of Mesh Plate tube always bring something special. I’m testing my burn-in tube rig actually. It’s good to power up old tube slowly, to prevent ‘heart attack’ since...

Sometime I’m curious how hot your tube is? Well, this short experiment will give you some idea. Different tube may have different thermal characteristic (simple logic: the higher current on the filament, expect higher temperature). Off course we can use...

I dig some of my collection and find some AZ1 tubes. Basically, I have several tubes, but short word, they are separated into 3 brands, Philips Miniwatt AZ1, Valvo AZ1, and Telefunken AZ1. I don’t use P-Socket on my system,...

I would rather call this as “beauty in the dark”… No longer perfect in terms of construction, slightly off-center for the mesh and triangle, since probably over 70 years old tube. But… It’s still a nice collectible item. Since the...

In the middle of the night, after finishing my tube rectifier dual socket modification, I prepare some tube rectifier to test the new socket. I think it’s gonna be nice to evaluate the sonic of some rectifiers to 😉 Actually,...

My rectifier socket got problem, accidentally, the one of the pin was broken yesterday. So I fill this weekend to repair it. Since I used to use Octal and B4 based, why don’t I put two sockets to simplify my...

It’s a cool weekend, we are entering rainy months. I continue soldering my Ultimate Power Supply. Today, I solder 8 pcs of MUR860 and 70 pcs of Black Gate F Series. Done in 3 hours, not bad huh....

Some of you have emailed me asking to finish the Gainclone – Black Gate Power Supply project, and well, I’m about to complete it with some modification. Here is the “sneak-peeks” 😉 The rectification section is made dual, total 8...

It’s over midnight. After my previous mod on my Aikido Power Supply section here, it’s time to test it with RGN rectifier. I pick my Tefefunken RGN1054 Mesh Rectifier (before, I use Russian 5U4C, not a bad rectifier though). The...

Due to generosity of my friend, let’s call him “Mr. S”, I manage to secure two more RGN Rectifier and add it to my collection. Welcome the Telefunken RGN 2004 and Telefunken RGN 1054! Both are mesh version! The RGN...
