RE: Hitachi CSP 680 - ex crustytv

Tried a 10% each way adjustment of R911 - no significant change to HT which now reads about 112V. Only 10.3V on the 12V rail, it has been suggested by another friend of mine, may not be sufficient for...

RE: Hitachi CSP 680 - ex crustytv

OK, some progress... having replaced TR41 (with a BC640), R908 (with a metal oxide 2W resistor) and C906, the symptom is no longer "no raster", but "no video" - there is clearly a raster as deflection...

RE: Maplins Universal Modulator VH89W

The Maplin modulator looks just like my short lived Philex. I hope my purposes are served by the JVC video recorder I have, for a while, but I am keen to hear others' experiences.

Parts on order. Postal issues may delay things a bit, but with luck I'll have a raster by Christmas.

RE: Hitachi CSP 680 - ex crustytv

@irob2345 Hmmm... oddly they didn't show me that particular line when I searched. Now I only need to solve the resistor issue.

RE: Hitachi CSP 680 - ex crustytv

@katie-bush I don't think so - it's because their entire stock of BC640s is on the other side. £15+ surcharge because of it. Other supplier can sell me ten times as many for about half what I'd pay in...

RE: Hitachi CSP 680 - ex crustytv

Oddly enough, due to a special Transatlantic shipment charge, it is cheaper to buy 50 BC640 from one supplier than to buy 5 from another. If I go for the cheaper deal and anyone needs any, I may well ...

RE: Hitachi CSP 680 - ex crustytv

OK - well, one of my suppliers has BC640 for the same price as BC327 and subject to an order multiple of only 5, so I have put that on my list. Once I get to the bottom of the resistor requirement, I ...

RE: Hitachi CSP 680 - ex crustytv

Had time to investigate this a bit more. TR42 (a 2SA673) may well have been OK but one leg fell off during testing. R908 - meant to be 22K, 5% tolerance - is reading short - it's a large-ish resistor,...

RE: Bought an old PYE TV, absolute beginner

I'm wondering how the channel indicator on 1980/81 Finlandias worked... each had a "shows this when not tuned" but it seemed to change with the actual tuned channel.

RE: Bought an old PYE TV, absolute beginner

Hmmm... this is one of those teletext sets that advocated putting ITV on "2" and BBC2 on "3" - as did some early Thorn teletext sets. Why it was initially done on my grandad's first Luxor I have no id...

RE: 1972 Hitachi CNP865

CNP865 is a PAL-1 chassis set. UHF-only version is CNP860, PAL-2 equivalent is CNP190/195. Still working on my CSP680 which has had two losses of HT and a loss of colour so far, but these sets are int...

RE: 1970's Tandberg CTV1 & CTV2; additions to the Crustytv collection

Posted by: @richardfrommarple @katie-bush The early G8s had a front convergence panel, but needed the speaker grille removed to access them. Some rental customers worked out how to get to them, and t...

RE: 1970's Tandberg CTV1 & CTV2; additions to the Crustytv collection

Earlier CTV2s (2-2 series models) were among favourites in my past. We had one at my Infants' school (a 103), and my grandfather had one (a 105). The 103 broke down once, with a manifestation of the s...

RE: Hitachi CSP 680 - ex crustytv

Instead of the cathode of CR39 connecting to the cathode of VA903, it connects to the cathode of VA901, via a wire link inserted as VA902. This seems to actually be how the board is marked. The vacant...

RE: Hitachi CSP 680 - ex crustytv

All transformer voltages, and the chassis-mounted transistor and resistor in that part of the circuit, check out. The main capacitor, a 470µF/200V can, is outside the range of my meter, and could poss...

RE: Hitachi CSP 680 - ex crustytv

Tests today showed, once again, no HT with plug K out of the deflection board. I have the power audio PCB out, and it seems to differ from the circuit diagram - VA903 is absent, solder is smooth, like...
