Please help! Tube amp issue
It would be a lot easier if you got a photo of that Magnavox amp and copied the parts layout and wiring scheme! Trying to build any amp (tube or transistor) from a schematic is not a guarantee of success! See my post above! It is always best to di... 
Please help! Tube amp issue
Parts layout is very important in any amplifier design! Keeping the power supply/transformer away from the input stage, wire length and routing ... Grounding issues? Did you use star grounding (tieing all grounds to a single point on the chassis)?... 
What will a preamp do for me?
Maybe the PS 4.6 would be more appealing if the price was $3995! Don't be fooled by the belief that "if it costs more it must be better"! That is a rabbit hole that too many have fallen into! 
What will a preamp do for me?
There's a one-owner PS Audio 4.6 preamp for sale now on EBay. $395.95 and free-shipping from PA. Seller is "buy-wrightjtt". This is an excellent sounding preamp, equal to units costing thousands! I have owned two of its predecessor - the model IV.... 
Can you live with your current speaker until you die?
@shkong78 : I will bring a gasoline generator and ferment/distill vegetation to produce ethanol for fuel! And a SS amp (Bedini 25/25) plus a CD player with variable output, along with CDs. of course!  
My first Tube Amplifier
@atomheart411: see my two posts above! I'd go for a pair of W5's or a nicely restored Dyna ST70 with 6L6/KT66 output tubes! 
My first Tube Amplifier
Alternately, you could buy a nicely restored pair of Heath W5 mono tube amps. 6L6 PP with outstanding transformers (Peerless). A true classic! I have a pair, so it's an easy recommendation! Can be found on EBAY! 
My first Tube Amplifier
The venerable 6L6 (late '30s) is an excellent output tube. Limited to about 20-25 watts for a PP pair. Its sound quality is limited to the make of the output transformer. Cheap ones, like in the Mesa Boogie, have problems with bass and high freque... 
Top Ten Rock Vocalists
Tony Martin with Black Sabbath! Superior to Ozzy! Sadly unappreciated! 
Setting up 2 power amplifiers to setup at once help?
@noromance  I own enough amps and preamps to equip a store! I have my favorites, too! Same for speakers - their sonic signatures are certainly more easy to discern! 
Setting up 2 power amplifiers to setup at once help?
@noromance With two amps of different gains the bass and mid/high sound levels won't match! That would hardly make for good listening! The OP wants to give his father the Denon and keep the Yamaha for the Polk's. I personally would do the opposite... 
Setting up 2 power amplifiers to setup at once help?
@noromance The OP is a novice! My advice is correct! The two amps must be identical for bi-wiring to work properly! Let him install two jumpers per speaker and use just one amp at a time! 
Setting up 2 power amplifiers to setup at once help?
Yes, the top diagram is correct! Just get two jumpers (a few inches of wire will do) for each speaker. Forget about bi-wiring (the correct term). Use only one amp at a time with your two speakers - after you install the jumpers! 
Setting up 2 power amplifiers to setup at once help?
There should be jumpers between the two reds and the two blacks. Get them! You still cannot bi-wire the A7's because you don't have two identical amps. 
Discontinued equipment that you wish were still here. What do you miss or think will miss?
Too bad JBL couldn't re-issue the L166 Horizon! A much better speaker than the L100! I have a pair!
