Whats a good recommendation for a 2203 replacement set?
I didn’t like the Mercury’s- anyone?
Ive never had to buy any transformers but if I needed to I probably would'nt look any further than one of this sites sponsors ' Classic Tone ' .
What didn't you like about the MM trannys? the tone clone is a copy of the dagnall.. The primary impedance is most important 1.7k I think? Did the internet get you to believe in the old paper vs plastic mythology?
Did you replace good transformers? Or was there something actually wrong with the originals?
Were you convinced that changing transformers would make the amp work/sound better?
I know that tone is subject to the individual, but to my ears, Mercury iron has a sort-of "tearing paper" sound between the midrange and top end. Could be modern tubes, I don't know? Friedman amps have this sound, though I don't think he uses Mercury Magnetics transformers. Classic Tone iron seems to sound closest to Marshall OEM.
Classictone. Excellent tone, quality and a good value.
Watch the PT B+ voltage vs the voltage rating of your power tubes.
Heyboer or Merren.
Yeah I did remove good stock ones, because a few guys recommended that, and then internets said convincing stuff.
The Mercury’s lost the “whomp” the stock ones had and now the thing reacts to strings real linear.
Linear is for stereos.
Not sure if that's sarcasm, if not, you've had some bad advice.
A 1981 2203 was fitted with the classic transformers that people generally attribute to why the old amps sound better. I'm certain you wont get any responses here other than "put the originals back in".
Let’s be clear: the Internet’s can be blamed for a lot of bad information we mistakenly followed in hindsight.
Speaking of which, I DID as suggested and visited the above advertised xformer site and may try a set from them!
I was looking for more headroom, Plexitone squeal & sizzle than stock.
Well the Super Lead 100w used exactly the same transformers so you're barking up the wrong tree there. You need to investigate other mods or a different amp.
I have use and will use again Marstran specc'd Heyboers (the Metro ones are the same AFAIK and made by same manufacturer). I have also used Merren OTs and was very impressed, pretty sure he winds his own, bit more expensive. I have a classic tone OT in JMP clone - yet to fire up. I found the Mercury in a JTM45 build very sterile (and yes linear) I replaced it with one of George's metro specc'd -103s and the amp was transformed (ha, ha...) with much more complex tones.
I do think in a true 'metal' amp the Mercury might do well.
Oh and I am always looking out for original Dagnall's and Drakes, although the PTs are often blown so take care.
I think you nailed it with the term “complex tones” for the effect I’m seeking from the new set I need
Internet... internationally not entirely true
.. put the originals back in, that's the sound you're chasing..
A. First of all, a different transformer will not give you more headroom. That's not possible.
B. If you want a different sound, try using different preamp tubes it can make a big difference.
C. Changing transformers will not make any magical change in the performance or sound, it will be almost the same.
D. There is nothing wrong with stock Marshall transformers, and they are really good transformers.
There is a lot of misinformation on the internet concerning transformer changes.
Most of it is just BS sales hype.
Some sales people will tell you that your tone is going to be vastly improved - it's just bullshit.
They want your money and they don't care what your amp sounds like.
In other words: You were taken by sales BS.
The way to change / improve the sound of an amp: is in the preamp and speakers, not the transformers.
Partially true: the mistake was not selling $300 transformers I paid $220 for with the amp complete, nor becoming good friends with a great American shop in Sergio and at the time Paul.
Things I learned from them and about their shop and product developments were priceless. You can’t but that and I respect Mercury in all they do.
Any question I had, any design, brand, year, core structure,”square vs round” magnet wire got an immediate answer. plus the reasoning behind it all “why this why that” they were very patient.
I was glad to pay, and I did make $50 when I sold that set also- but was it just a waste of time that took me? Or did my own tone-chasing madness push me I don’t know exactly.
But I have many tubes and speakers in my collection - thanks for those kind suggestions - which is why I sought out that last unknown fork in the road to me which was interaction of the OT & power supply.
The originals went on CL years ago very quickly
This is probably the best Transformers set.
