Hi Roland / Dave I'm inclined to be a little more cautious. While tensilised mylar of either three or six or twelve microns will work, and any coating which ...
Hi Frank, In principle, I agree. Unfortunately, from the pragmatic standpoint, the reality is that it is impossible to be sure that any rebuild will replicate...
Dear all, I recently asked the group to comment on the various (comparative) merits of the original Quad II amplifiers versus the new Quad Two-forty version....

Well I've never heard the two forties but I understood they were supposed to be as close as possible to the 'real' Quads so frankly I'd stick with your...
For a long time I have known that if did not keep the cancel button of my 33 in the switched on position (i.e. tone controls cancelled), I would get some nasty...
Sounds nasty. AC is pretty unlikely. More likely it's an oscillation in the tone control section of your 33. Check the motherboard and underside around the...
Hi Everybody, I own a pair of 57s that I have been storing at my parents for some years, my girlfriend being not overly keen on them being in our 12 foot by 12...
Dr. John I just sold a pair of original Quad II's to a guy who had borrowed and been using Quad Forties for a couple of weeks. He has just sent the Quad...
Hi, Hans, Did the 33 and the 303 get the necessary revision? With dried-out capacitors (electrolyts have an average lifetime of 10 years) you can expect all...
Dr. John I own both Quad II and Quad II Forty and use them to drive the Quad ESL57. In terms of musicality, the Quad II win especially in its original form (if...
... I just had Esmond at Dada Australia do up a couple of 303's and a 33. I only use one channel of each 303. Even my mp3-age son was impressed with the...
You'd need ten times the power for twice the sound volume if 13 Watts from QUAD II isn't enough. I think Forties with matching pre-amp were connected...
Hi All, I have just purchased a set of cloned Mark Levinson HQD Stands (http://www.marklev.com/systems/index.html ) and I am in the process of rebuilding my...
I see a pair of Decca Tweeters on ebay just now for £300 Item number: 280256798294 Ribbons too. Fred.  ________________________________ From: marc_can_1...
Generally a bad idea as the sweet spot now becomes somewhere at the hight you put them. So you get the full spectrum only when you are standing, or sitting and...
i am using decca/london ribbon tweeters i bought on audiogon. They are the same tweeter as far as I know, but in a horn rather than the box. I'd like to know...
Stop! Any 40-50 year old amp needs to have a cap change. Quad II is no exeption. Especially the elcos. You think it sounds sweet with tired, dry caps? Listen ...
Cheers Jeroen I think I'll try it! I usually slouch down pretty low (with my feet up!) when I'm listening to records anyway, so it sounds like this will be...
Thanks I agree. I'll check the boards. I did that once in the past but will do it more thoroughly now. I'm curious whether replacing the TR 107 will do the...
I think we are sayinmg the same thing in many ways Dave. Some years ago, I looked carefully at Gary Jacobson's work to date, and at the various rebuilt and...
Maybe one of the other new QUAD amps, the Classic II, which seems to be a copy of the original II (and is rated at 15 watts) may be something for John to...
Matt As you said, you just have to give it a go. I imagine you'll lose imagining and treble definition, but it could still sound acceptable, especially to ...
Thanks Lee (and all). I will stick with my Quad IIs until such time as a "modern" valve amp can supersede their magic. For Graham M, I'll get back shortly...

... Agreed 100 percent. The problem is that the owners of older weared down equipment likes it as is. That their baby is performing far below what it did as...
Thanks Fred. Given what the vendor is looking for, with shipping - that would set me back almost $1,000. More than what the (pre-rejuvinated) 57's themselves...
I bought them off a local guy (Kitchener, Ontario) from EBay. They were his Uncle's who had passed away last year. The 57's were long gone - all he had left...
There can be large differences between the original values of physically identical capacitors - also how they age when (and where) active in circuit. ...
Implied worth doesn't assure sale or profit. Maybe worth declaring an interest and see whether these or other drivers they might have could be bargained for....
