Hi group...

The replacement VU meters I had ordered and posted about some time back, 
were received yesterday, which isn't too bad for having come from China.
I have to admit that I was a little nervous about the transaction.

The packaging was just 2 small boxes in an placticized envelope, but they 
arrived in good condition and in just a little over 2 weeks from the day 
they were ordered.

I installed one this morning in the 1960 S-W I've been working on and I have 
to say I'm impressed with how well they work, with 10dB changes showing up 
as exactly 10dB apart.

They fit the panel opening and the mounting holes perfectly, the only thing 
I'm not crazy about is that they use spade connectors for the audio input. 
There are two small "tabs" with holes for supplying ~2.5Vdc for the LED 
backlighting, which I'm not using at this time, but I did test them anyway.
Of course, they are not in a metal housing, but black ABS(?) plastic.

You can google them as "TR-45 VU meter" if you'd like to know more about 
them.
