New acquisition now an owner of an R1155/L

[domm1kta]

Hi all,

Once I cleaned out a few spiders and gave the front panel a light dusting this is what I have...

I thought it was the N model... actually it's an L model. The drive seems smooth and all the switch contacts appear to work.

Just initial photos but the set on first appearance looks in reasonable condition and the front panel and the dial seems to be intact. To my untrained eye I'd say it hasn't been hacked about this either.

I believe the missing valves are for the DF but I will probably be wrong.

The cork panels in the chassis, missing one of the long ones. Of the others one is in place and three are loose. I suspect replacing the missing one the dinning room table cork mat I use for drinks need replaced with something nice and modern as it is the right thickness hihi....

Missing three of the front panel thumb screws.

I'll blog the restoration although probably will not see much done this side of summer. I expect will wander down to RAF Duxford (7 miles SE of QTH) to see the Lancaster mock up at some point. http://goto.glocalnet.net/bosradio/m...otogallery.htm

Hi Dom

Has it been re-wired or are those PVC wires original? It does look like the D/F valves are missing and unfortunately somebody's screwed in an aerial socket where the 'meter deflec' should be. You can also see where the connection has been made to pin 1 of the jones plug.

Looks superb and original,though i could be wrong.Have one myself that has not been touched and was working well last time out.

Hello Dom.

Yes,the DF valves are missing and were often removed for amateur use,which also helped to reduce current consumption.It looks as though the leads to the DF valve grids are also missing but easy to replace.The insulation was changed to p.v.c. sometime in the 1940s so is probably original on your 1155.The DF valves are still available but other DF components are not so easy to find.It's fortunate that your 1155 is still mostly intact.

David,

The PVC covered wires certainly are not new but weither done in 40's or 60's/70's is probably anyone's guess.

Yes noted the meter deflec mod. What should this have looked like a switch that went from 10 o'clock to 2 o'clock?

Hi Dom, Yes that's correct. I've checked my front panel and there is a small hole where the bolt for your aerial socket is, so hopefully it's been fitted without any drilling

Thanks.

Now the small issue/bit of fun at rallies of finding the switch
Do you have a high res image of it front and rear? Any markings or type?

Don't suppose you got one spare? Thought there used to be a R1155 website selling spares but cannot find it now.

Dom,you're probably thinking of John Swingewood at g4cvu.co.uk. His website seems to be broken at the moment, but I don't recall him ever listing switches.

I've never seen spare DF switches for an 1155 at a rally (or sold separate from a set at all ) despite having looked for a few years. Still, you never know your luck when you sort through boxes of junk at swapmeets.

Hi Dom,

It's not very good but here's the best photo I have of the switch.

I doubt you'll ever use the D/F capabilities of this receiver, so why not fit a dummy shaft and buy a repro knob from g4cvu? Leaving out the D/F valves also makes it easier to find a suitable heater supply
