    Thanks Randy,

    I was gonna have him do it but after some research I think not....

    Did you find that people didn't like the amps he builds? I have considered buying one of his amps, so I'd love to hear what your research turned up. 

  2. Hi Scott, 


    I did not acquire it from Chris Keller. I don't know what the restoration entailed, but might be able to find out.


    I took the amp to a local tube amp repair place here in Portland, Or. Dawson Amp Repair. https://dawsonamps.com/


    If you call and talk to the owner Matt, he can tell you about what he did to fix the cord and his opinions on the amp from a build perspective.


    Can you DM me your email, to send more pics. Its alot of editing to get the pics posted on here due to size limits




  3. This amp is quite rare in the states. It was made in Japan in 1978. The faceplate is perfect and the box is in amazing shape! I had it in with a tech awhile back and he fixed a couple things that were scratchy in the channels. It's good to go now.
    I intended to build an office system around it, but that's not going to happen, now that we are going to make the office more of a dual purpose space with a fold out couch in it.

    I have listened to it a bunch, and it sounds fantastic plus it has the ability to run MM and MC carts, but the sirens call of vacuum tubes has me hooked and I must let this go.

    Here is a link with more specs and info:
    It's heavy, about 50lbs and to ship it I believe it would need to be in a crate to insure safe arrival. I would be happy to meet within a 200 mile radius of Portland, OR.

    Looking to get $1000 for it. I'll include PayPal fees in my price, but will also take Venmo, Zelle or Check. Shipping costs are on the buyer.

    Happy to answer any questions

  4. I've had this for under a year and while I am hesitant to get rid of it, I just don't need so many power amps around. I dove head first into audio 1.5yrs ago, ended up with 4 tube power amps, and now need to thin down a bit.

    I just had this in with my tech to fix the power cord and insure everything is running properly. 100% tip top shape.

    The sale will come with 2 quads of 6bq5 halo getters. One GE and one RCA.

    As a bonvoyage, I did a back to back with my Will Vincent St-70 and to my ears this sounds better than the Vincent, it just doesn't sound better than my Sayes SET 45 to me.

    Asking $850 shipped and paypaled, with a discount given to local pickup ( within 150 mile radius of Portland, OR) and F&F. Will be packed very well and insured when shipped.

    Happy to answer any questions.

    Unfortunately, it is not just "lights" that affect the electrical circuits in a home. Any appliance, motor (fan), freeezer, fridge, HVAC, etc can affect the electric circuit in your home and introduce "hash" (RF junk) into your audio system. Dimmers usually have a switching MOSFET circuit and that will introduce buzzes, clicks and other junk back into the house circuitry. 


    The "quietest" type of light would be a good old incandescent type bulb. It is just a resistance filament, so it is quiet by nature. Flourescent, LED, CFL, Neon, etc type lights are noisy and can introduce humm / buzz into the house circuitry easily. 


    To help attenuate these types of noises, I have had good luck with Tripplite ISO-BAR power conditioner / surge protecters. 


    They are high quality and get great reviews. If you try a Tripplite unit, ensure it has the "isolated filter banks", not all the Tripplite units have them, but most do.

    I now have 2 powervar Powe conditioners/isolation transformers now. Would you still suggest this tripplite iso bar knowing that I have these? 

  6. I often use my amp thats a SET and 1.8 watts per channel, through my La Scalas, with all different types of music and it sounds fantastic. I typically listen around 70-75db.

  7. I listened again last night with my sub on and the thing I have noticed is that with the ported mod the sound is cleaner. The bass seems less boomy and more real where sound is concerned. It doesn't hit you like at a concert, but it feels like it rounds the sound out in a very nice way. 


    I will mess  around some more with tuning after we get back from our trip, but I can say, I'm no longer disappointed that I built this. Its a nice addition to the system at this juncture and I will tune the ports a little more when I get back to see if I can gain just that last little bit that the DATS v3 curves are showing me I can get.
