Yes, friends Sony betacam BVW-35P work.. We played back few of his tapes.
But tape I recorded on my BVV-1 don't have picture but have record audio. Probably worn out video heads.
Interesting thing is that Sony recommended to replace uper drum with video heads after 1000 hours..
I found D-Sub...
I found that gear (dark blue arrow) that turn reel with tape around drum is very worn out, and looks like ordinary plastic, maybe it's hard plastic, teflon? because this is professional recorder..
I suspect they did not have put on ordinary plastic although it looks like ordinary plastic (very...
VTR don't have fast forward only rewind and forward as recording, but problem repaired!
It was damaged belt that turn gear that turn take-up reel. I replaced belt.
Now is everything work mechanically, still I dont have player to see if VTR recording..
becouse I see someone turned few...
I don't know why, but yesterday I put betamax (I don't have betacam oxide tape) and try to start recording and rail take tape around drum and drum started to rotate and few second after stopped, motor didnt rotate tape and tape become loose, and I got SLACK error. What that can be?
I read eprom from BVV-1 VTR, and I got this.
What is that file because I was hoping to find and change timer to zero.
I know it is not eeprom and this can be programed once and erase with UV,
but this eprom is suspicious to me. When I conected multimeter to chek voltages on eprom,
and when I...
So, I discover something that I will describe and hope that someone with more knowledge will know where is problem,
but still without schematic this is problem too.
Cyan arrow mark is small motor that start rotating by few milimeter, and then stop rotating...
I dont know what is that motor...
Yes. Lights illuminate, fuse are good, and I found Hour meter (1000 hours) maybe It needs head or electronics service every 1000hours?
As I can see when I push my finger on rail, mechanics return to the starting position, which is very likely that mechanics are good.
Belts are good, its not...
I got incredible Sony BVP-3P Color Camera 3 Saticon tubes
in working condition with attached Beta VTR model BVV-1PS but I think Beta dont work? :-|
I put Betacam tape not Betamax but VTR dont respond, It wont rewind or anything.
I dont have batterypack, only power supply. Maybe battery need to...
I got another 25 CXY11C gunn diodes. They behave very strange (probably because they are old) Datashet say that working voltage is 7V dc, but they oscilate on 5V. So I checked them all and I probably destroyed 8 diodes before I figured out they work on 5V dc and NOT ON 7V Dc like datasheet say...
Today I am making small gunn oscillator with WR90 flange by GM8BKE design. I don't have waveguide.. so I am making one just with parts from I found. It is finished, and work!
Cavity is from original gunnplexer Microwave Associates model MA86656D
operating frequency 10.525 GHz
Mullard datasheet say that CXY11 operate from 8 to 12 GHz
I dont see why they shuldnt operate in this cavity... BUT I saw this shematic:
http://www.microwave-museum.org/exhibits/mwm-033.htm...
So I made this setup. Not professional, but I have WR90 detector with movable short and attached gunnplexer. I put all of 25 pieces of CXY11C gunn diode in it like picture from datasheet say that flanged side is chatode or negative from power supply, and only 2 of 25 oscillate. I dont know why...
Hi!
I bought 25 gunn diode from eBay 2 years ago.
**broken link removed**
It is possible that all of 25 dont work? Yesterday I put one in gunnplexer and dont work. I put another one and change polarity and nothing.
Model is CXY11C and they work on 7V and 140mA datasheet say, but in datasheet...
