Another receiver...Leak 3200...Some questions
Like buses, I've never had a receiver and suddenly I have two in a week.
Unlike the Yamaha (my recent thread), this seems to work fine: the relay clicks when it's switched on, everything lights up like Blackpool and there is sound from the headphone sockets via the radio. I assume the speaker outputs work but don't have any DIN male sockets, if that's the right term, and am having trouble finding any online. Is there a way of connecting speakers to these some other way? Bare wires or something? The back panel confuses me, links and pre amp/main amp things I don't really get and will probably leave alone. I've looked online, but there's not too much about these. I am assuming, and I know this is very stupid question on this forum, that there are no valves in this that I might want to replace? |

Re: Another receiver...Leak 3200...Some questions
Just search for DIN Speaker plugs, plenty on Ebay and elsewhere, no valves to worry about in this one, nice looking unit, hope it works well when you get your speakers connected up.

Re: Another receiver...Leak 3200...Some questions
This is a transistor design, so there are no valves. The things you can see at the back are output power transistors.
You can temporarily attach speakers using bare wires held in place by sharpened matchsticks or cocktail sticks, though it's obviously not ideal. Nice looking 70s receiver - I think they were made by Rotel. |

Re: Another receiver...Leak 3200...Some questions
According to an old forum thread the Leak 3200 is basically a Rotel RX-402 in Leak clothing. That being so the attached owners manual may be of some help. Note that the Rotel version doesn't use speaker DIN plugs. This eBay seller is offering suitable plugs with screw connections so no soldering required:

Oh thank you for the manual! That is terrific. Made my day.

Re: Another receiver...Leak 3200...Some questions
Just be careful doing this. My son did it with an Armstrong 400 series receiver. It left a tiny thread of wire behind which shorted the speaker terminals and blew the unobtainable germanium output transistors on that channel, trashing the unit. The speaker terminals on the Armstrong are a different pattern and shorting would be a lot easier than the DIN ones but it is worth being careful

Re: Another receiver...Leak 3200...Some questions
Indeed, it's important to avoid any shorts with amps of this era. There's no protection, so any shorts will lead to the output transistors going bang, which is a major repair.

Re: Another receiver...Leak 3200...Some questions
Thanks, I'll wait to get some proper DIN speaker plugs because I'm cack-handed at the best of times and if anyone is going to short something fannying about with cocktail sticks it'll be me.

One thing to be aware of is that the hole diameter for the speaker cables can be tight/too small for some heavy duty speaker cables, similarly the cable entry shroud may be tight/too small for some heavy duty speaker cables. Same issue would probably apply with similar DIN plugs from other sellers. David |

Re: Another receiver...Leak 3200...Some questions
... in which case, you'd be better off using "normal" speaker wire.
0.75mm sq. lighting flex is ample for most things. |

Re: Another receiver...Leak 3200...Some questions
I think they may have expected a a graphic equaliser to be inserted here as well as the other uses.

Re: Another receiver...Leak 3200...Some questions
I see doing some searches that many of the experts on here do not like DIN speaker plugs. Do they actually degrade the sound quality, or is it jus that they are a bit fragile.

Re: Another receiver...Leak 3200...Some questions
It's now a long time ago but I used an amplifier with DIN speaker plugs for many years with no issues whatsoever. However if you're a fan (I'm not) of big chunky speaker cables DIN plugs are a problem as already mentioned.

Re: Another receiver...Leak 3200...Some questions
Personally have never encountered a problem with 2 pin speaker DINs in terms of sound quality or fragility.

Re: Another receiver...Leak 3200...Some questions
I've only ever had issues with speaker-side (female) DIN plug and socket arrangements, as they tend to fall out quite easily if/ when the speaker is moved, or the cable gets lifted about whilst hoovering, etc.
