Dave,
Do you use it with R2R and/or other tape formats, as well as vinyl? If so, how does it work? Which produces the best results?
Thanks,

The QD-1 has been re-wired. The solder connections are now good.
Looks great. Looking forward to hearing your response. Remember that my experience is to turn it down if I really hear the rears. Just enough where they aren't simply an echo of the front. Also, I've seen little effect on most digital sources for reason I don't fully understand.
But on good LPs, especially single point stereo miking, you can get some real depth and sense of space. Interestingly, the opposite extreme of heavily mixed and overdubbed stuff is where you get discrete, sometimes downright startling, discrete stuff from the rears.
Just live with it an experiment for a while.
Regards,
Dave
What effect, if any, does it produce with stereo FM? Also, have you ever tried it with mono recordings?

The QD-1 has been re-wired. The solder connections are now good. The pots and 3-position switch were cleaned. The DVM indicates the wiring, switches and pots are functioning as intended. I won't know for certain until I try it, perhaps by the weekend. I have to prepare some speaker leads to work with the crowded binding posts on this thing, as well as re-assemble a pair of speakers.
I briefly battled the urge to substitute heavier gauge wire for the solid copper wire. But, fortunately, I've been inoculated against testosterone poisoning (doesn't a vasectomy have that effect?). Given the size of the tiny soldering tabs on the 3-position switch, anything larger would have been extremely difficult to solder and would have resulted in a messier project without commensurate benefits.

Steve,
Check your email.

I have a pair of K-77s and a pair of CT125s. Either are yours for $150 including shipping. Send an email or PM if you're interested.

I have a set of Speakerlab plans I got from a forum member. They're 35 pages in pdf format and are 23.7 MB in file size. The limit for a pdf attachment on this forum is ~ 3 KB. Page 8 of the instructions alone exceeds the limit, therefore, attaching the document page by page is not possible.
If you send me a PM or email with your email address, I'll try to email it to you, and/or anyone else who is interested.

Happy Birthday to Amy and to you too dtel.

Nice find for both the assenbly and the HiFi engine site. BTW, that little "high hat" knob for the slider was used on zillions of older instruments in that era. That's not a Dynaco unique part. If you have an electronics junk yard of any kind in your area, you could probably prowl it and find one. The last tube tester I had used the exact or very similar knob. Good luck with the project!
Thanks for the tip Mark. I'm sure I can locate an acceptable black knob. I don't want to lose points for originality.[

I ran across this valuable resource while searching for a complete version of the assembly instruction manual for a Dynaco QD-1. Others here have undoubtedly seen the site, but I hadn't, so I'll share it now so that other blind squirrels might find this acorn.

Due to the need to totally rewire the newly acquired QD-1, I
located a pdf version of the manual that includes the assembly
instructions.
The version attached earlier in this thread (and ubiquitous on the Internet) was from a factory
wired unit and lacked the pages regarding assembly. After repeatedly finding the pdf of the manual
with the same serial number, I stumbled upon: http://www.hifiengine.com where I located
a pdf version of the manual that included the assembly instructions.
Pages 14 - 23 of the full length version are attached in 2-3
page segments to this and the next three posts. The size of the entire pdf required that it be broken down to smaller files,
each within the limits of the forum's server.
BTW, the Hi-Fi Engine site looks to be a valuable resource
to the audio hobbyist community. I'd not
run across it before. I'll post a separate
thread in the Updates & Modifications section about the site.

ARGH! Well, that soldering can be fixed up pretty quick. Shouldn't be too bad. Those knobs have been used on many things. You might be able to scare one off an old tube tester or old low end reciever with slides. Hope it works out.
Mark,
Fortunately, the round metal knob is there. The black plastic knob on the BALANCE CHECK has been replaced by the white plastic thingie.
You'll notice a ready supply of new red wire. I'll try to keep this original in case I want to enter a conours d'elegance. [

Dave-
Now I wish I'd beaten your friend Ron on that QD-1 for $15.51.
As the attached photo shows, the QD-1 I "won" on eBay after making a best offer of $35 ($48 including shipping) was a kit that appears to have been built by Stevie Wonder . . . when he was still "Little." The soldering is abysmal. Note the completely unconnected wire in the lower right. Most of the the red wires . . . wait, they're all red . . . have soldering iron brands on the insulation.
Like yours, mine lacks the little black plastic handle from the BALANCE CHECK, otherwise it's all here. I'll clean it up and replace all of the wires. It should be better than new.
I doubt I'll get to the point of testing it this weekend. In addition to resurrecting this, I need to reassemble the second pair of single driver BR speakers.
EDIT: 9/21/13
My usually empty social calendar now has a gathering of old (that's redundant) college friends to watch MSU lose to ND, while demonstrating just how mediocre both teams are, as well as the rest of the B1G (not including the Buckeyes, which might be the real deal).
I'd like to hear about Ron's score. He got a good deal. Actually, I don't feel too bad about this purchase, especially given the prices that some QD-1s have fetched on eBay. One eBay optimist is currently asking $9.95 for the sticker from the bottom of one of these.
-
Dave-
Tell Ron I'm glad he beat my sniped bid on that item. I really don't need 2 of them, but at that price range I wouldn't have minded.

Those look very nice. They are the prettiest Speakerlab SKhorns I've seen. Not at all like the 4 black plywood SKhorns abused by me and used to deafen adolescents in my 70's DJ biz. The factory finished Skhorns weren't as well finished. If they're not the best looking Speakerlabs, they must be in the top 5. I can't imagine any looking better.
-
Jeff-
Sad indeed.
You and your father are in my thoughts and prayers.
-
FYI, Khorns on eBay.
Snipe a bid and they could be a bargain.

A QD-1 just sold on eBay for $15.51 with shipping. My sniped bid got outbid. Since I already "won" one my max bid was $15,67, not enough to meet the bid increment, thankfully. I don't need two of them.
-
Apparently, they're gone. I contacted the nearby seller about the Khorns and received the following:
"craigslist 4064030506
9:41 PM (11 minutes ago)
to 1da82ed277be34.
Sorry, they are no longer available."

All of the drivers and crossover components for the Webb and the LS3/5As were purchased from Falcon Acoustics in the UK. I think it' may be OOB now also.
Jerry Bloomfield of Falcon Acoustics still runs a fine operation. I helped my non-DIY friend recap his KEF Reference 101 monitors using tested and matched Alcap electrolytic caps (same as OEM caps) from Falcon Acoustics, and the results were fantastic. With his revamped Conrad-Johnson MV75-A1 75 watt amplifier, my friend's system sounds great.
I do like the British speakers, but my preference is for the Klipsch Heritage series speakers with upgraded crossovers and internal wiring. With T-amps and tube amps, they just sound magical to me.
Richard-
Glad to hear that Falcon Acoustics is still in business.
I agree about the sound of refreshed Klipsch Heritage (plywood and T-35s) or the equivalent (or better) horn-loaded speakers compared to British, such as KEF. My KEF based speakers sound good, but Klipsch sound alive by comparison, especially when played loud. My BBC LS3/5A DIY with KEF B-139 TL subs sound fine at reasonable levels, but they're very inefficient (which PWK equated to distortion) demanding a lot of power to play loudly.
One is much more likely to walk down a street and come upon an open door expecting to hear a live band, and then be surprised to see La Scalas or upside-down decorator Khorns at full boil than to find KEF, Warfdale or even Tannoy sounding like a live band.

No, but the fox did. Squeeze him here, maybe he'll pass another.
Now I have to get a turntable. In a moment of weakness, Years ago I gave away my AR XB with SME 3009II and Shure V15 III. Must've killed too many brain cells in my stoner days to do something that stupid. I'm into this project too far to quit now. A turntable is in my future.
I've got my eye on one on eBay just like, including cartridge, one of the two I used in my mobile DJ biz 37 years ago.
