Speaking of OTA Television Antenna's..... I came across this Youtube channel: Mr Hop To It : https://www.youtube.com/@mrhoptoit7835/videos In this video, he shows several DIY OTA Television Antennas that he has made. https://www.youtube.com/watch?v=42ZAEhKsBVs And tests how well they perform in a re...

I found this Manual/Schematic.

If you look at the schematic.
There is a test point (TP4) going in to IC 001 at pin 2.
Maybe you can tap in to that?

I have a few 310A tubes. Those things go for a lot of money on Ebay, but when you want to sell them the antique dealers want to steal them from you. :x I don't sell on Ebay. Only use it to BUY. I was just hoping to find out what the big deal is between the LP & SP. The prices can vary a lot! Ye...

Seems there was a lot of speculation about just what the term 'punch' meant. Okay, Here's my take on the meaning of "Punch". Seller's of these Tubes, wanted an easy way to distinguish between the two hole type patterns that these Tubes use. Thus, making some audiophiles think that they ar...

A mesh plate tube's functionality is essentially the same as a traditional solid plate tube: the amplification of an audio signal. With that said, the introduction of a precise mesh pattern on the plate will alter its role in attracting electrons . Whether this alters the listening experience veers...

Sorry, for putting this SPAM here. But anything that can finally silence Microsoft's Contana , in my humble opinion. Is a good thing. Plus, it's free! :mrgreen: A Tech nerd friend sent me this link to O&O AppBuster: https://www.oo-software.com/en/ooappbuster I can finally get rid of all the BLO...

Yeah, There are multiple things to take in account, that can effect how well the Tube performs. Materials used to make up the tube. How good of a vacuum was pulled when the tube was sealed, and amount of impurities left in the tube. Are they (N)ew(O)ld(S)tock, or used. Have the tubes been "Burn...

Reply from Mark at BlueGlow Electronics: small punch is pretty close to wire mesh, they are the earlier made of these and some say they sound better. I think the large hole tubes are just as good sound wise. There is no electrical difference, just difference in how the holes were punched into the m...

My sister and her husband were in to Tube Audio Equipment, back in the 90's. A lot were newer designs that were Pre-Amp, and even Main Amplifiers. I'll see if they have heard of this term. They got back to me. But they too have never heard that term as well. :( Using the link I first gave, I looked...

Hmmm......... I wonder if it is just some term that some of the younger Vacuum Tube enthusiasts use, because they thought it was more appropriate? My sister and her husband were in to Tube Audio Equipment, back in the 90's. A lot were newer designs that were Pre-Amp, and even Main Amplifiers. I'll s...
