![]() When configuring a download, you get to select the output quality (highest, 4K, HD or regular with different resolutions) or choose to export only the audio to an M4A or MP3 file. PullTube will start fetching the video data right away so you can see the video name, duration, and a small thumbnail. Download videos hosted on YouTube or Vimeo to different output sizes and formats Worth mentioning is that, if PullTube detects that the video is part of a playlist, will offer to download the entire collection: will fetch the data for each entry and handle the downloads consecutively. Note that you can also add a video by dropping the link on top of the PullTube window. The PullTube user interface is represented by a small window where you get to quickly paste the video URL. Video downloader that can import links with drag and drop and can detect playlists The app can handle playlists, allows you to select the output quality, and can even extract only the audio. PullTube offers you the possibility to download videos from both sources (YouTube and Vimeo), while other platforms might be added at a later time. Thanks to Bruce for sharing his work and supporting the DiY community! I've found this to be educational, sometimes frustrating, sometimes expensive, but overall great fun, and have something unique to show for my efforts.Sharing videos via online hosting services, such as YouTube or Vimeo is a common practice, yet streaming the content might not work as expected if you have a slow internet connection. Strange how quickly the sounds improves as the parts "bed in". ![]() I didn't think that this would be a problem as it's not AC, but is it worth re-routing these too to keep them away from everything else in an effort to eliminate that last bit of hum, or coud it be the misbehaving LM317 making noise (it sounds like 50Hz mains hum)?Īnyway, the one working channel has gone from sounding dreadful to sublime. Some of the heater supply wires run quite close to parts of the signal circuit and coupling caps. I'm using DC for the heater supply (per the design, again built up on a solder tag board). At least my tubes have been stress tested now! The correct part has been ordered. Now it works fine on one channel, but on the other it does not seem to be limiting the current very much at all - hence the overheating resistor in the B+ supply circuit. It also seems that using the LM317AHV is not a good idea. Should I be able to eliminate this completely? The hum is still audible with your ear up against the speaker, but you can't hear it from a couple of feet. I attached various ground connections to the negative rail on this board, whereever it was physically convenient - this turns out t be a very bad idea! I've amended the layout to a star earth with each ground connected seperately to this one point - the hum has been significantly reduced. HT - I'm talking about the B+ circuit, which I built on a seperate solder tag board, physical layout being pretty much the same as the circuit diagram. This way, I can balance the tubes easily without having to dig around for my multimeter. I bought a digital voltmeter panel display unit (0-200mv) from ebay for a few dollars (from China, inevitably), and connected this across the 1R resisitors through a rotary switch. Just one mod to the original design I thought I should mention, incase it is of any interest to anyone else. ![]() On the plus side, it looks great, and this project has kept me out f the pub for many evenings! Very strange!Īny hints on where to start looking greatly appreciated. ![]() Is this a problem?Īlso, there is a strange noise (a sort of dirty volume pot sound) at a certain volume when no feedback is applied. I built the HT power supply on a seperate turret board, and the various points in the amp circuit which need grounding are connected to the negative rail on this board, rather than to a seperate star/bus ground elsewhere. It works, but there is a loud hum, which I'm assuming is a grounding issue somewhere. ![]() I finally plugged in my amp today, after waiting for Russian caps from Ebay and exchanging tubes. ![]()
