Not a pretty sight: inside the Yamaha CT-610II

Receivers and transmitters for that matter are not as complex as people think. they are, but they aren't
That picture shows a fairly large AM/FM tuner.
I have a rig that is the size of a pile that comes out of my dogs arse, and it covers 136-476 MHZ on both modes of operation, transmit and receive.
It has a nice little keypad on the front of it too. CTCSS and DTMF. :yes:

Here is a ct-610 ( not II ) I just picked up at the Salvation Army thrift store. It had the manual taped to the top. I paid 15$. The manual says that there may be differences in the Canadian model in regards to voltage switches, so maybe there are other differences as well.
Can anyone tell me what the resistor connected to the line wires would be for? There is no capacitor or mov across it. The power is switched on the transformer secondary side. The plug is not polarized like new equipment.

Is it perhaps an RF choke and not a resistor?

Here is the CT-1010 to help complete the Yamaha CT-series of nudies. 5-gang tuning cap and a very nice sounding tuner. Great match for the CA-2010/1010 integrated amps.
To complete the views, go here for the CT-7000 nudies. http://audiokarma.org/forums/showthread.php?t=68033

Well, with the Philips power amp giving me a bit of a problem, I started to pull out the Sony STR6060FW to rehook the Bozak Symphonys and with all this discussion I grabbed the CA/CT610II pair instead to re-evaluate them and 1st impression is that they pose no threat to the 6060 or for that matter the Philips 797 or even the 796 receivers. For sound alone on a stong station I'd give it the edge on the Rotel JR-S301 and H-K 630. I'll keep it hooked up for a week or so to see if I "burn in" and appreciate them more.
They deliver the music but there is little or no life. At normal listening level they seem to present the emotion of listening to a system at background levels while reading the Wall Street Journal. Instruments individually sound masked or veiled. Almost what 1 heas when there are massed instruments. Radio announcer male vocal has more sibilence than it should.
As for the packaging, it reminds me of cereal. You open the huge box only to find it half empty and then read the fine print that disclaims false packaging by stating contents may settle.

This an old thread I happened across and read my post. Since then I picked up another CA610II as mine had some severe scratching on the faceplate and I was looking for a parts unit.
Subbing the the 2nd unit showed the 1st while seemingly good sounds as described while the 2nd has more life and the veil is lifted. Now I can hear why persons like the sound; on some speakers it does very well such as The Smaller Advents Loudspeaker.
I have had more time with the CT610II and though I do not like the no guts in the box I have gotten over it but might not be as forgiving had I bought it new. The performance compare to a number of other tuners leaves me with the same feeling as my Sherwood S3300. Maybe not the best in specifications but very well balanced in engineering, execution and sound and listening pleasure. The Sherwood gets the nod in this comparison but I can see living with it. On the CBC last week they were playing some records. On the Sherwood SEL200 receiver that's tuner is based on the S3300 and the S3300 the record noise was easy to identify and was noticeable while with the Yamaha it was only barely discernible. The Yamaha was feeding the Yamaha CA610II into the Smaller Advents while the S3300 was feeding the SEL200 into the Klipsch Heresy IIs and the speakers may have made the difference.
All in all, I now think that for the going price of the CT610II, it is good value. I am thinking about getting another Yamaha for the 2nd amp and if I can what other tuner models have the same width and maybe depth, I might look for a higher rated model, maybe a CT800 or the CT600.

Question for the Yamaha groupies. I have the CT610II but have not found either an owner's nor service manual for it but have located an owner's manual for a CT610 answer it physically looks the same, front and back.
In a listing of Yamaha models I found online there is listed a CT600 and the CT610II but no CT610. There is a 2-year production gap between the CT600 and CT610II in the listing. I also notice there is the CT400 and CT410II but no CT410 and there is no production gap between the 2 listed models in the timeliness. Is there an error in the listing or was there no CT610 or the CT610 was not exported?
I thought Sony was in some ways tough to follow because of their export vs domestic market timeliness bit it seems Yamaha may be just as confusing with their model designations.

I once had a CT-410 (or CT-400) in immaculate condition. The dial didn't light up, so I looked under the cover to see what bulbs I needed. There were no bulbs to replace. I guess Yamaha felt there was no need for that extra cost. You think your CT-610II looked underwhelming inside....I could cover the entire CT-400 circuit board with the palm of my hand.
These units were designed to match up with their corresponding amps.
