Interesting..indeed.
Can't help myself from asking : What? is all that Ugly/messed goop on the coils actually for ?
Never previously seen that particular bodge. Hopefully it wasn't pricey.
As aside .. IF determined to refit the Crossover covers on.. neatly ?
It is possible to fit nutserts to the coffin top bit and then use screws in lieu of the drilled out rivets.
Yer Welcome
I should imagine it's glue to hold them in place as they're quite heavy and can strain solder joints - I've seen it used on inductors and large capacitors. Nowt out of the ordinary and not indicative of a 'botch job'.
Danilo, thanks for the info on the nutserts. I'll pick some up for the next time they're opened but to be honest they can stay like that as they're securely mounted to the front panel with washers protecting what's left of the plates.
Thanks Adrian. I do believe that you've nailed it.
Sorry.. Not even close rationalisations.
The LSU Hf crossovers are Very well made OEM . Being prior to the Harmon International 'takeover'.
They were well assembled solid units.. by any yardstick.
Far better than subsequent HPD ones for example
OEM these have a U shaped Ali bracket that goes under the PCB around the Coil lams (white taped bits) and has threaded ears that press against /fit the Coffin lid.
Where two screws fit, tightening the; clamp, transformer/coil and PCB Solidly together. It ain't moving.
Some bungler has removed the Ali hold down entirely.
Gawd Only.. knows why?
Even IF the goofy assortment of caps precluded the Coffin lid from Fitted adequately.
A simple additional bit of ali plate across the tops of the coil laminations would restore the structural integrity of the Factory Hold down design.. Quite neatly actually.
Easier to do IMO than Slopping Goop unbelievably messily everywhere. Even onto on the windings fer Gawd's sake ??
Other small trivia: Sily Cone is (Usually) corrosive.
Fair chance that the Goop (if it is Silicone) is eating away at the slopped on Coil windings .. as we type.
IF silicone? best remove it... Sooner rather than later. OEM Coils can be 'difficult' to find
Frankly not massively concerned..Mostly because they Ain't Mine :lol:
Does seem a shame though.
Hopefully the above is result of DIY adventures.
Hey ! we all learn something every time. Mistakes are essential to advancement.
Seriously problematic though... IF one paid $ for this quality of work.
I'd be looking for my Baseball bat TBH..
Danilo, thanks for taking the time to elaborate on your concerns. For clarity, I already posted that the crossovers were re-capped by Paul Coupe (of RFC).
They are not a "DIY job" nor is Paul a "bungler". He has a stellar reputation on matters Tannoy and I trust him not to have encased the autoformer and base inductor in a corrosive substance. I suspect he has recapped even more Tannoy crossovers than you have made doom-laden posts on AoS. :)
