I recently bought a Tandberg TCD330, seemingly in excellent condition. The seller told me the unit had been recapped, cleaned and lubricated around 3 years ago by a top local audio technician and then shortly afterwards calibrated and aligned by Tandberg Zentral Service in Germany. I have the...

I have a partially restored 2270 that appears to work great. One of its minor quirks is that the bass tone control knob makes a rumbling noise, but only for about the first 10-15 seconds after the unit is powered up. Could this be a dodgy cap on the tone board? Anyone have any ideas? Happy...

While adjusting the motor azymuth I managed to over tighten the adjustment screw mechanism so that it now turns in it's housing and serves no purpose. To get around this I found a simple solution by glueing the motor mounts correctly in place with epoxy. Now everything works fine, but I notice a...

These look very much like A25's in a nicer cabinet, without the treble attenuation pot. Dynaco 1 by Jon_Bawn posted Sep 6, 2020 at 1:00 PM Dynaco 2 by Jon_Bawn posted Sep 6, 2020 at 1:02 PM Dynaco 3 by Jon_Bawn posted Sep 6, 2020 at 1:03 PM Anyone got any thoughts? Cheers, Jon

I have been using and enjoying these funny Dynaco's or Scan Dyna A25 / M25X hybrids (whatever they are) and whilst the sound is good, am toying with the idea of swapping the 2 small Peerless drivers out for a single tweeter, either the original SEAS H087 or perhaps the new equivalent Seas...

Hi all, Does anyone have any experience of these: https://www.benl.ebay.be/itm/PAIR-of-8-full-range-drivers-for-Lowther-Acousta-or-upgrade-Celestion-Ditton-15-/202226545769 Seems like a great idea- adding an 8 inch full range instead of the passive radiator, in parallel with the existing bass...

Hi Braun fans! I have a wonderful pair of LV1020 active trips-amped monitors that have had a full professional recap and also most of the transistors replaced.... They have been extensively cleaned, adjusted and tested by a competent tech but still have intermittent issues... Since the...

Hi Braun fans! I have a wonderful pair of LV1020 active trips-amped monitors that have had a full professional recap and also most of the transistors replaced.... Since the restoration both units suffer from intermittent, scratchy noises (not volume dependent), particularly when the amps are on...

Dear all, My 2270 has a funny quirk whereby for the first minute or so after cold start up, any adjustment of the Bass level causes a strong subsonic rumble. After that the bass adjustment is fine, and I hear no issues with the sound... There is also bass rumble when the Low Filter is engaged...

Hi guys, Does anyone know what these speaker stands are? Very nice quality, heavy... 61.5cm height / 65.8cm with spikes / 7.8kg each / 5mm solid steel top plate, sand filled, spikes top and bottom, footprint 39.2cm x 31.4cm Thanks in advance if anyone has an idea? Jon

Hi everyone, My much loved Pioneer SX727 has developed a nasty noise on one channel, and I wonder if someone can suggest what might be the cause? The receiver is in very good condition, and has worked fine for years, but developed the fault after being switched on for longer than usual (8 hours...

Dear Friends, Today I was lucky enough to acquire a pair of Braun LV1020 active speakers- huge, impressive beasts from the early 70's with internal tri-amping. They cost a fortune in their day, and seem to be in original and very clean condition inside and out. But the sound is way of what you...

Hi everyone. I have the chance to buy some very sensitive speakers (Wharfedale E70 / 94dB / 8 ohm) and fancy having a dabble in tube amp sound. I have never tried tubes before (old or new), but am pretty happy with my vintage solid state Marantz 2270 / Dynaco A25 set up... I am wondering if...

Hi all,I recently had my Marantz 5220 fully revised by a specialist tapedeck tech. I will copy a list of the work done below. However, after the revision there is still audible flutter, particularly when recording, and particularly on things like acoustic guitars and mandolins. In fact it's...

Good evening people... Does anyone have an idea why my Marantz 2270 puts out less volume (per same position on the dial) than my Marantz 2230? Sound is fine on both... Marantz 2270 runs much hotter.... I didn't check DC offset or bias... but I wonder, could it be a cold solder joint on the...

Hi guys, I am replacing the headphone socket on my 2270 as the original fell apart in situ... My question in what to do about the two 47 ohm resistors that I believe were wired to the + L and R channels in the old socket and to a common ground. The new socket is a Monocor one (apparently the...

Hi folks, after a bit of general advice here. I have in recent years brought back into service a THORENS TD160 MK1 turntable that I've had for ages but stopped bothering with vinyl some years ago. Like so many others, and with a decent library of records, I started to get back into it, but so...

Hi! I recently acquired a very clean SX727, really beautiful and with a nice soft sound. The previous owener had lovingly "restored" it but not really touched or adjusted it technically, reading between the lines. The SX727 sounds good, but as is so often, one channel is much stronger and...

Dear All, I have a recently required 2270 that has been "almost entirely recapped" by it's previous owner, who claimed to be an electronic tech. Certainly the main power caps are indeed new, I didn't take it apart in detail to find out more.... On line and tape inputs (incl digital sources) it...

Dear all, I have the opportunity to purchase a marantz 5220 in new wood case for a decent price (around $300 with new belts and lighting). It would look great next to my 2270 and complete a vintage setup with dynaco speakers. Question is this: I know tape decks got better through the 80's and...

I recently purchased a Rotel RA960BX integrated from the German auction site and it seems to run hot (almost too hot to touch on a 4 ohm load. I've read other reports of this being the norm, but opened it up anyway to have a look. As you can see, there's obvious heat damage to the plastic...

Hi there... Can anyone identify these (possibly early) Dynaco's please? 3 Way, no port, 8 ohm, same size (and apparently cabinets and grills) as A25XL, 4 position tweater control on the rear. Any comments or knowledge of them gratefully received. Cheers, Jon

Hi! Does anyone have any tips on how to clean old, dirty, bextrene bass drivers and even better how to return the old, faded colour to a new-looking black? I'm thinking damp cloth with fairy liquid as a start. Crazy part of me wonders how "back to black" car tyre restorer would go... ???

Hi! I have acquired a pair of B&O Beovox 5700 in very good condition. They have the same high and mid as the venerable Celestion Ditton 66 but a different woofer and passive radiator (10" rather than 12"). Replacement, even newly designed, Ditton 66 crossovers are available. What does anyone...

What does anyone think? Safe to run 2 sets of speakers (8 ohm and 4-6 ohm) on a recapped 2270? Results in a 2.6 - 3.4 ohm load.... Would be only at very moderate volume for shortish periods... Safe or not?
