    Denon POA 4400 DC Offset

    Hi People, I've got a Denon 4400a that has a DC offset of 45mv on both A and B channel outputs. When trying to adjust the bias as per the service manual I cant reduce this figure down and lower no matter what adjustments to the variable resistors for the bias. I'm wondering if 45mv is too...

    Jolida music envoy monoblocks

    Good afternoon all. I have developed a "hum" in one channel and suspect it may be somewhere in the internal power supply of one of my monoblocks (jolida music envoy.). I have scoured the internet trying to find schematics without success. Any suggestions? They sound beautiful when functioning...

    B&K ST-140 convert to monoblock

    I had posted about this a while ago, but still haven't found anything definitive. I have two ST-140 amps and would love to convert them to a pair of monoblocks, as they were originally available as an option way back when. Does anyone have literature or the expertise to advise in specifically...

    RCA MI-112182 Monoblock Tube Amps

    Been wanting a pair of RCA PA/theater monoblocks for a while, but never pulled the trigger -- until now. Bought a pair of these for probably more than they're worth. The seller states they're from the collection of an ex-RCA engineer, which I'd normally be skeptical of, but could be true given...

    Stromberg Carlson monoblock

    Rescued this from the local ham radio club. A 6V6 P-P audio amp. And a 12AX7 and a 6AV6. Stromberg Carlson (at least most of the tubes were branded that). Probably came out of a record player console. With bass, treble and volume controls. Changed the 6X5 rectifier to a 6AX5, and replaced...

    What is wrong with my system?

    Hi everyone - I’m posting here because individually I think my components are all good, but together my system is not making music, rather is is making bright bass less noise. Honestly, I’m thinking it’s no one component, but the matching of components that is causing this issue. I would like...

    Need help with Goldmund VRS M2 monoblock

    Long story short- I found a single Goldmund VRS M2 mono amp at Goodwill. I stuck around for about an hour to see if they brought the other one out, but no dice. I'll check again tomorrow. Anyway, I found out why such a high end piece of equipment was at Goodwill. One of the MOSFETS took a major...

    7189 Monoblock Project

    Hello: I am posting this in the hopes someone can shed some light on some nice old iron I just acquired. I have two nice PTs and two nice ultralinear OPTs, all pulled from two mono 6BQ5 ∕ 7189 amps. These were taken from organs from the early sixties. The amps have 6GH8s and EL84s in...

    Newly acquired pair of Sansui Q-15's!!!

    I just recently purchased a pair of Sansui Q-15's from Rick /aka Johnny Fever and couldn't be happier! It really was nice dealing with someone who knows and appreciates these early Sansui Tube amps as much as I do, and it showed in his packing job as well! Damn near bullet proof for safe...

    Kenwood L-07M Restoration (1)

    Hey all, I figured I would post some updates on the restoration of my L-07M monoblocks. When I first got the L-07M's, I used them on and off for a few months before getting them serviced by my tech in MA. Apparently, he only replaced the capacitors that measured out of spec. They have been...

    Custom Tannoys/amps Identification

    Hey y’all! I just picked up these units with Tannoy dual concentric drivers in what appear to be custom built bass reflex cabinets with a mono amp built into each one. The drivers need to be refoamed so I’m having a local place do that. The cabinets look to be custom built and are HEAVY. Each...

    Brooklyn, NY - Kenwood L-07M Pair with boxes.

    Filthy and on that auction site, but unwilling to ship. Someone local might be able to get a sweet score there. I say this because the seller is obviously not motivated to maximize their profit at all. Not mine, no affiliation. https://www.ebay.com/itm/303300612627

    Preamp ideas for a pair of Fisher 100 monoblocks

    After dabbling with my pair of 100 monoblock projects for months, I think I'm just about done and ready to put them to use, but alas, I don't have a proper preamp. Originally I had intended to use my Fisher 500c as a preamp, but very quickly realized the jacks on the chassis that I had taken for...

    Akai M8 Rebuilds

    Hey All, Just sharing the rebuild of my Akai M8 monoblocks for my man cave. With a new baby, renovations, wrist reconstruction and work I have finally gotten a chance to start putting the right channel back together. Generally have to wait until they're all in bed or get up really early. I...

    Odyssey Audio - Stratos Mono amps?

    Anyone have experience with Odyssey Audio amplifiers? A pair of Stratos Mono amps (stock) came up for sale and I'm intrigued. This seems to be in line with what I'm looking for in terms of finesse over muscle; plus I have no need to drive power-hungry speakers. Odyssey seems well-regarded by...

    Soundstream M-3 Tri mono amp

    I went away for the weekend to see a concert with the wife. We decided to hang out for an extra day and check out stuff around town.I happened across this thing for cheap at a flea market. From the nothing much I've found on the net, It seems like it may be a minor score at least. Pretty hefty...

    Hello, New member whose poor 2-channel system has been woefully lacking and has finally decided to make amends with his ears. First stop is power amplification. My criteria seem to be at odds with the market (and possibly my wallet), and I could really use some sage advice. Criteria after lots...

    This is one of a pair of tube amps I restored. Removed from a 1950's Magnavox console, recapped and upgraded. Sound terrific.
