@@hallesarts There are a few parts which need to be oiled manually.

@@mohammadmakiabadi6868 Like less than 15W I believe

@@mohammadmakiabadi6868 Just added a slightly bit of inductor there and picked a suitable fet😹

@@uecmitsuimarinedieselengin873 I wish it was shown in the video 😀😁

@@inductivelycoupledplasma6207 Hah exactly. Thanks 🙏

​@@uecmitsuimarinedieselengin873by the way, I can't seem to find any data on the 4CX500 tube you used. Do you have any information about it? Thanks 😅

@@inductivelycoupledplasma6207 Oh it should be 4X500 tube, by eimax, maybe I typed wrong sorry.

@@uecmitsuimarinedieselengin873 ahhh, cool. I found it! I recently obtained a CV1883 tetrode with very similar specs. 500W plate and 30W screen, but with a 20W grid and 112.5W heater! I'm going to get some more as they're very cheap. Nice to see that you got some good performance from a similar tube

​@@uecmitsuimarinedieselengin873thanks! I found it. I am working on a VTTC with a similar tube (CV1883), a tetrode rated for 500W anode dissipation. Hopefully I can get some good performance from it, as I haven't built any vacuum tube circuits before

@@inductivelycoupledplasma6207I was using like 235pF doorknob for the tank and around 18-19 nF for the feedback.

@@uecmitsuimarinedieselengin873 thank you :)

@@inductivelycoupledplasma6207 Hah nice! I read about something that they put a piece of metal sheet in the relatively cold area inside the bulb(cold point) to make the mercury condense on them and give it a better property to start.

@@uecmitsuimarinedieselengin873 I smashed one of my bulbs accidentally, and yes, there is a braided metal strip in the base of the lamp, near to the coil. So yes, you're right! I'm assuming the lamp initially strikes through CCP and it transitions to ICP. There is also a coil in series with the one around the ferrite, which is simply wrapped around the tube, with the magnetic field down the axis of the discharge, like in our ICP experiments (air core) and I believe it's purpose is for starting. The lamp operates at 230kHz. Very nice bulb, although I burned the phosphor on it using the HFSSTC circuit hehe

@@inductivelycoupledplasma6207I think that second 'winding' is used like a resonator to induce high voltage to help with the start, I can see it on my 2.65Mhz induction lamp as well. What does it become when the phosphor is burnt? I am curious

@@uecmitsuimarinedieselengin873 in my lamp (which is different to yours, with external ferrite rings), there is a whole second coil, would around the glass and not the ferrite. I suspect this is for starting. The phosphor turns black when burned. There's now a huge dark spot on the bulb haha

@@mohammadmakiabadi6868 I think so but it will need a matcher in between.

@@mohammadmakiabadi6868 Of course, you can send me an email then I could reply to it with the schematic attached. Link in my discrimination

@uecmitsuimarinedieselengin873 thanks a lot 🙏 💓 💕 ❤️ 💗

@@TheTemporalAnomaly Actually there are via holes around the grounding plane there. Yeah you got it right, the problem lies in the nature of Class E, too high Drain voltage. Usually it should be 3.x times the supply voltage for a standard Class E, however here I actually slightly decreased the conducting angle to let the maximum Drain voltage drop a bit to make sure it lies within the safety region. Thanks for your comment!

@@Earthcomputer-d9t I am willing to help, just email me and we could chat.

Ok thanks 🤗🤗

@@T2D.SteveArcs Hi mate, yeah during the test the engine was set to -34rev/min. This vessel isn't equipped with a variable pinch propeller😄. There are different kind of governors which could be used on diesels, such as the constant speed type, constant torque type. However the main engines usually are equipped with the constant speed type to avoid the runaway in a storm. Nowadays the ME engines use E-governors which could be set to be speed or torque controlled on the computer.

@uecmitsuimarinedieselengin873 😎 thanks for your explanation/reply you're awesome mate 👍👍👍

Hello friend, C1 is a 0.1uF ceramic capacitor which is used as a filtering capacitor for the gate bias.

yeah
