Cambridge Audio A1 missing a speaker connector

[Walter_DH]

Dear all,
I have just bought on ebay this well know amplifier. It's a Cambridge Audio A1 V 3.
It was quite a bargain but there's an issue (I was informed). As you can see in the attached a picture, one of the banana plug connector in the rear panel (where a speaker is connected) is broken and it misses a small / terminal part.
May you please suggest me a store (on the web) where I can find the missing part or, even better , the part number?
Will it be an easy fix?
Thanks and regards
Walter

It will be a slightly involved fix unless you can find the part you need. Maybe Cambridge has the entire assembly (red and black connector) to use to replace that same part in your unit. It might be a piece with both speaker connections, all 4 connections in one piece. If that part is available, the part you need might unscrew and be used on your unit. If not...soldering...

I would buy a couple pair of the Dual Binding Posts from a vendor of your choosing, ebay, electronic store on line and replace both sets with these dual binding posts. Gogle images of dual binding posts to see what they are. These will need to be installed on a plate that will bolt to your unit as they probably won't 'just fit right in' to what you have and will need to be soldered to the wires that are there on your unit. This is not hard work but if you do not know which end of soldering iron to grab or can't get a plate to mount the binding posts, it is better left to a technician.

Thank you for your reply and help. I have basic DIY/electronics skills. As soon as I receive the amp, I will open the case and see the broken part to replace it.
Maybe if I'm lucky, it will be sufficient to replace just one connector, like these...

Kind regards
W

Hello everybody. The Cambridge Audio A1 amplifier has just been delivered by the express courier. Please find attached some pictures which show the case , the speakers connector (with the missing terminal ) and a particular of the phono stage.
I haven't tried it yet because here in my office I don't have any source or speaker. Plus I have to replace the British plug with an Italian one.
Some questions/considerations.
1. The speaker connectors seem proprietary : the binding posts are not bolt to the rear panel; they're a single plastic part with 4 threaded connectors . If I manage to find the missing bolt, I will fix the problem. Otherwise it won't be possible to install an after market binding post / banana female plug.
2. This model has an ordinary transformer, not the valuable toroidal transformer. Bad luck.
3. As you can see in the last 2 pictures, there was a cable harness unplugged from the phono stage/board. I don't have a turntable so I don't plan to use the phono input, but anyway: what should I do? Should I reconnect the cable to the board or leave it disconnected? What is its function?

Many thanks and regards

ps. this is the picture of the missing terminal. It's a threaded bolt with a plastic red cap. It shouldn't too hard to find a spare part

update. I bought just one red plastic binding post and managed to bolt in the threaded female conncector. Everything works fine

Hi Walter - Please can I ask what you typed in to purchase your binding post? I’ve the same issue with my A1 M3 Cambridge Audio Amp (I know this thread is quite old now so you might not see this!) - But I’ve bought ones online and they didn’t fit - so would appreciate your help in me trying to get all 4 (I know -I lost them while moving) - thanks in advance!

39, Hopefully some one can help you.
Walter hasn't been here since Oct. 2016 so I doubt he'll answer. But maybe I'll be wrong.
