Finally I have one Zenith!

[Komet]

Thank you all, the restoration will start in these days


@ Colorfixer
My Zenith is 110V NTSC. It's been imported from US last year

@ Glenz
The Phonola K8 uses a Philips chassis because this brand has aquired the Phonola for making different style cabinets for his TV and sell these in Italy. It's very rare and is the last Philips color chassis with tubes. 110 degrees CRT.

I have the KM2 (multistandard version of K9 chasiss... a real monster...) and two K11 (early and late version).

Here you can see this chassis

I powered up this Zenith... I have an image but tremble the vertical lines... probably bad sync separator or horiz. oscillator.

I have changed the main capacitor; and as dieseljeep suggested, I increased the value of capacity. I found some NOS capacitors at my lab, made in Italy by CREAS under Sprague license... One of these is a four sections, 200-200-75-50uF... I have put in parallel the 200 and 75 sections for use like the original 270uF capacitor, and the 200+50uF instead of the previous 150uF.

Now the set seems work good, in these days I have make a good setup

Ok, good news, CRT is ok

I have some problem with color decoder. Yesterday when I adjusted the color saturation I see the test bars changing color, like if I adjusted the hue control... After a suggestion by the old owner of this Zenith, I inverted the position of the two 6KT8 (1st color amp/cathode follower and sound amp/sound limiter) and now I have the correct chroma when I adjusted the saturation knob.

But seems I have an AGC problem, the saturation changing during watching, probably some tube has gone (like 6HS8 AGC/sync sep.)

Komet - Thank you so much for the link to that awesome vintage TV museum blog and thanks for the info on the K8. Look forward to your progress on the Zenith.

Cheers! Glen
