A Sansui G-something. I have one of the 30-35 watters. Ugly as sin, but supposedly not too bad sounding.

Yep, G-7000 to be exact. It's not too bad looking but not my cup-o-tea either. I have to say, it does sound amazingly good though. Much better sounding than the 300B amp it replaced. And fortunately, we finally talked him out of using those stupid nasty and shrilly Klipsch RB-75's and switching over to the DCM TF350's. Much better sounding speakers, 110% so. But anywho...

BTW Dave, what's your take on BSC and series resistance combined? Not needed like Jim said? Not that I'm doubting you Jim, just curious of what Dave has to say about it.

Time, old boy, time. Dave doesn't have much of it at present (I know the feeling).

Anyway, generally, with a compensation circuit in place, you're unlikely to require any additional components in place. If I can avoid using it, I do, but if not, I don't get worried about it.

Hmm. Vintage Sansui recievers. I like. 🙂 I even like the looks, but I always did have odd taste.

Not really helpful, but I'll leave it alone at any rate just because.

What about you Chris?

I'm of the opinion that matching driver to enclosure design should mitigate if not eliminate the need for series R, particularly with the higher output impedance/low damping factor SET amps that I tend to use.

On the one occasion I tried to "remedy" an experimental /intentional mismatch with series R, I didn't like the results. This was commented on when I built my first pair of Brynns earlier this year. The FE127E just sounded more right to me than either the FE126E or FF125K with correction.

As for BSC - one of these months I might try it, but I do take exception when told I don't know what I'm missing if I don't use it with any full-range driver. Well, of course not, but neither do these helpful folks know what I'm expecting or hearing.

I'm sure he is busy. I didn't mean anything by it. I've been running a little ragged myself lately.

Don't get me wrong, I'd rather not use anything inline with the signal, especially after the amplifier, but space is somewhat at a minimum in my room, and whether I'm using the cardboard boxes or build a couple of horns, I'm still going to run into using BSC regardless. This is just more or less a test bed for me to play around with a few ideas and learn a few things along the way.

The big Sansui, Marantz and Technics receivers of the late 70's were certainly the best looking of the bunch, even better looking than the McIntosh receivers. And boy, did they ever make some of those things massive!

Oh yeah... that sweet Sansui sound!

These are two receivers we bought way back when. The Sansui 4000 in 1972; 45 wpc at 8 ohms (didn't notice how badly it needs cleaning until I looked at the photo.) The Yamaha CR-1000, 70 wpc at 8 ohms, dates from 1976. I also have a Sansui 350A (25 wpc) in my office which I bought used some years back.

Younger audiophiles condemn receivers, because to them a receiver is one of those 10 lbs wonders rated to put out 120 wpc into 5 (or 7) channels. REAL receivers are big & heavy--none of that switching power supply or digital stuff! :devilr:

IIRC, the CR1000 had an optional Class A operating mode (like it's integrated amp sibling the CA1000) - good for only about 10 watts, which wasn't quite enough for Dahlquist DQ10 - but I'd love to hear one today with one of my Fostex based systems.

Don't forget the Harmon Kardon twin powered series from the mid 70's HK330, HK440 etc., and the NAD 7020 - a sleeper giant killer if ever there was one.

Not unlike today, the better sounding models tended to be at the low end of the power spectrum (i.e. under 30 WPC).

There's something appealing about a single full enclosure that costs less than some of the high-zoot signal and power cables we use to connect the 3 or 4 components that it takes to replace their function.

Daniel's got my HK (630 or 740 IIRC -- 25V rails anyway) to fix the blowed up output stage -- my first real receiver was a 630 but quickly traded in for a Citation 11/12 (latter a kit)

And 3 NAD 7020s are lined up to become 2 good ones. The NADs sounded really good, but to get the sound and keep the price down they were built cheap and tend to fail sooner than the Japanese stuff.

Also on hand is a big Marantz. My favorite Japanese stuff in the day thou were the Onkyos....

ah, the 70's , :crying: how we do miss them :geezer:

soon to be an gritty (make-it all up) HBO retrospective series, starring Kevin McKidd as Peter Harrison, and Michael Chiklis as Ron Guy - "CAV-man" (private joke)

but now, back to our regularly scheduled programming

Sony/Coral holey baskets - suitable for the Vampyr?

Scottmoose said:
Amen to that.

FWIW, until Dave has chance to do the proper ones, 'ere be a roughed up set of plans a la Vampyr. Not pretty & the drawing isn't to scale, but the dimensions are correct.

If one had a pair of "holey basket" FE103A's looking for an enclosure, would the Vampyr, as drawn, be OK?
If not, what changes are recommended?

cheers
