Restoring in progress. Cleaning and lubrication. Waiting for new belts from Germany. Also needs new heads.

Erase: E4-200
Rec: R4-150
PB: P4-150

Hi,
I have found a used but good R4 150, alas the one only NEW P4 150 I have is under offer at the moment. However I have asked the potential purchaser to affirm by Monday, if not one or both are yours if required. The new/used heads would be £48. 00 plus postage to Norway, whatever that might be. If interested let me know & as stated if the NEW P4 150 is not taken , we can do a deal. OK?

Cheers.

Colin.

Sounds interesting. Is there any wear on that rec head at all? Or is it like new? Let me know if that potential purchaser winn buy it or not.

Best

Looks like this deck is coming from the UK. It has been serviced in 88.

See your email, good news.

The wear on the erase head can be ignored, if only for the fact the plastic around the pole pieces wears away (unlike the brass head of the 4000D which wears severely)
It is possible to alter the zenith so the wear over the head surface is more even.

Ready for new belt.

Vinylguru · 7th Jun 2015, 5:07 pm

Now it's almost ready again. New lamp for vu meters and new belts. New heads will be next. Then I will be ready to restore a Philips N4450 deck. But that will be another story.

Hi Vinylguru. Can you describe the lamp bulb and where you got it from? Wonder if its the same bulb as in the 1720L?

These bulbs work

I used one like this, but in 6,3V value.

Vinylguru · 22nd Jun 2015, 12:14 pm

New heads arrived today thanks to Doffery

Mint condition

Now I can play tapes again.

DOFFERY · 23rd Jun 2015, 9:43 am

Glad the heads arrived safely & you are happy with same,

Colin.

Restoration73 · 23rd Jun 2015, 9:14 pm

Heads look good - don't forget it's a good policy to demagnetise the entire head
block assembly before use. Keep the demagnetiser away from the VU meters though !

Vinylguru · 26th Jun 2015, 7:17 pm

And a new erasehead is on its way from the USA.

Vinylguru · 8th Jul 2015, 10:24 pm

Almost there. All heads are new.

Vinylguru · 12th Jul 2015, 5:53 pm

How come this happen? See video.

If I play in 7 1/2 speed, it will go straight through the capstan. See video.
