Re: Another MET1 on the forum - problems
Difference is so obvious that I didn't even have to go through extensive listening sessions to come up with following observations: Before (with new PS caps in place and small bypass 0.15uF Sonicap): - shy on bass/lower extension weak, - satisfactory instruments separation/clarity, although sometime...

Re: Another MET1 on the forum - problems
Here it is, what I believe to be almost final version. It has been running problems free for a couple of months already. Almost final version, because I plan on removing bypass SCP after I'm sure they are broken-in completely (500h) and see if I need them or not. Also, I replaced original 0.15uF 200...

I like a look of bare naked and exposed electronics.....here I said it.....admin wrote:Wow, that is beautiful. Congrats on the setup as it must sound great. Question: Do you plan to run the music fidelity without the covers permanently or that's just temp?

Re: Another MET1 on the forum - problems
Preamp is up and running!!! Well....at least it has been running fine for 30min. Don't want to jinx it but it looks like it will be ok. Went through all the components on pcb and found no fault elsewhere except the two mosfets in HV circuit and shorted cap mentioned above. Lesson learnt! Tubes alway...

Re: Another MET1 on the forum - problems
All channel are now operating fine. All mosfets seems to be fine (the best I could do without desoldering) . How the hell do I get rid off this loud HUM? It has got to be voltage leakage on one of PS caps. There is my favourite saying: "if you want to play, prepare to pay". It was from my ...

Re: Another MET1 on the forum - problems
The bad: After 12h MET1 died on me with loud pop, reduced, distorted sound and within a couple seconds dead. Resulted in blown fuse at mains and after replacing fuse the internal fuse F1 also blown. Some brief troubleshooting lead me to shorted small 0.15uF cap on SW channel. Why on SW only? weird.....

Re: Another MET1 on the forum - problems
Who's Mr. Jameson? Irish Whiskey :D Modified unit indeed sounds differently. First impression (first two hour after modification) is quite satisfactory: spaciousness, transparency and instruments upper range extensions were improved. Lower end was kinda thin but after about 10h I can say it's impro...

Re: Another MET1 on the forum - problems
Thanks to Jeffreybehr for being a mastermind of this operation. Thanks to Mr. Jameson for for giving me courage and steady hand while holding soldering iron over $7500 piece of electronics. Here it is up and running: http://imageshack.us/a/img211/2673/1z3.jpg http://imageshack.us/a/img51/431/iw0w.jp...

Re: Another MET1 on the forum - problems
No, I did not talk to him.
Why? Would there be any problem with Mundorfs in PS?
Based on my brief online research many people use them in power supplies.

Re: Another MET1 on the forum - problems
You just scared me off with 200h of brake-in time :) so I had to change my strategy: - Mundorf caps are going to Power supply together with small SCPs 0.33 and 0.01uF - For L and R channel I'll have Multicap RTX 2.0uF with SCP 0.33uF All parts ordered and awaiting delivery. Jeffrey, How did you secu...

Re: Another MET1 on the forum - problems
Jeffrey, As usual, Thank You for support, help, guidance :-) Finally decided to approach this carefully and go with Mundorf 2.2uf (cheap option) simply because I don't know what to expect. If I'm happy with caps change I will think of upgradig to SCPs. Also, why not to experiment with a few caps and...

when it rains, it pours...... I think I'll have to put the modification on hold for some time. The reason is always the same....money. It's kinda expensive but It's still less by more than twice the cost I may end up paying to fix my martin logan speakers.... I enjoyed my multichannel system for how...
