I picked this TV up today along with another shortly top be revealed, the @the_teleman kindly providing company and transport to fetch them.  There's not a lot of information out there regarding this model, except to say the 18" C-1851H was far more common and turns up more frequently than the 20" version. The 18" having a black plastic from, whereas the 20" in an all wood effect cabinet. Brochure here.

Interestingly, lots of German on this set too. Thankfully, I have the service date for this out of the red books.

Never seen this one before! Saw the odd sharp portable from the era.

I think Sharp used the name Linytron on more than one model. I have never seen a C-2051H but I remember the Linytron name and I saw a couple of the ones featured in Michael's service sheet. Mechanical tuner and built like a brick shitehouse!

Lyintron was the trade mark sharp used for the Toshiba black stripe tube.

We saw that chassis in Oz, too. A reliable, well-sorted design, the 22s and 26s were built in Sharp's factory at Fairfield, a south-western Sydney suburb. They had robotic board stuffing. Smaller sizes (like yours) came fully assembled from Japan.

Note the reverse-side PCB pins for module service purposes. Kriesler did that too, with their early releases. I never had occasion to use them.

That set was one of the first to have the Toshiba fully-self-converging tube.

Big thank you to @michael-dranfield for loaning me the Sharp manufacturer's service manual for the C-2051H, and some of his personal notes from encountering prior faults. Having an ex Sharp dealer in the VRAT house certainly has its advantages. 👍

I'll scan it over the weekend and make it available in the site library.

How about this for a photo, dating back to 1985 when I only sold secondhand refurbished TVs, look closely, what do you see apart from me??

Well I never, look who had a C-2051H for sale 😎 wish I could see the price on the red sticker.

1985, I was just 22-years old, you would have been 21 I believe.

Here's me as a 17 year old repairing a Rank T22 line output board.

@michael-dranfield Salora/Hitachi L on the top shelf? Also the little 10" Philips that had a loewe chassis?

I remember the little Phillips very well, it had an intermittent fault, the micro would lock up and the set displayed 88 on the led display, it turned out to be as I remember a dry joint on the tuner!!

These sets used double sided print and I think the tuner was used to join the earth's on both sides of the print.

Although it's nice to have some much-needed decent weather, one side effect being afternoons in the workshop hit 30C. This lasted well into the evening, and was still 25C at 05:00 the following morning, so not a lot of action this week.

Thank heavens, the heat has now subsided, so back to these recent additions. Today, I wanted to see the condition of the Sharp's 510JGB22 CRT. This uses the exact same JEDEC B12-262 socket as the A51-570X, so once again over to the Leader LCT-910.

To say, I'm blown away by just how much life there is in the Sharp tube, would be an understatement. Wow! Just Wow! Even better than the good one I have in the Fergy 3758. I had a feeling it might be good as ther was bags of cut-off. Anyway, as a result I would expect this C-2051H to have a superb picture, just hope the LOPT (which is TINY) and tripler (which is HUGE) are as bullet-proof as replacements will be as rare as hens teeth,

First thing that's getting evicted is C729, the big .47uF filter RIFA across the mains. Remarkably, it's not showing the usual fractures these RIFA caps normally all exhibit, nevertheless it's going. I think I will also be winding this chassis up on the Variac, it should be OK, unless anyone thinks otherwise.

I have two, just in case of that eventuality. 😀 I also have the B&K 467 is normally my goto tester, I just didn't have the JDEC socket for this CRT, typically the only one missing.

Re line transformers and triplers, a company in Sydney (WES components) still has stocks of "universal" triplers and Philips CTV line transformers. I was there yesterday picking up a gram cartridge for a repair and I asked the guy to check his stock of triplers, which he did. "Over a hundred" was the answer. And yes, they do ship O/S.

https://www.wagneronline.com.au/wes-components/ps/

Oh yes, in Oz we call them "EHT transformers" or "LOPT"s. A "Line Transformer" is used for PA work.

Prices are better if you open an account with them.

They also have a huge range of VCR parts.... That can't last much longer!
