Sandawa, Good Day to you Sir.
I saw a Marantz esotec PM6, not in good condition. Overheats and the tone control does not work. Cosmetically, its dognuts, so I didnt buy it. It looked like a hefty, heavy unit. Is this part of the VFET amps?

sir, ang galing mong tumingin ng surplus amps. i read your posts and almost all models you mentioned were vintage gems. Marantz PM-6 is definitely a good collectible model, if only it could be fixed. no, it is not one of those now rare V-FETs, which axel dahl (The Vintage Knob) thinks could be limited only to a few Sony and Yamaha amps made in late '70s.

Sandawa,
nyah ah ah. you're my guru Sandawa...I have this "sandawa surplus checklist" you see.
I've read all your Surplus posts and observations and have cut and pasted your surplus observations into a one page excel sheet that i keep in my wallet.
Everytime I visit thrift shops...i look up the units that I see against my "sandawa checklist". A few days ago I saw a Yamaha a-7 in a shop. But you only included the Yamaha a8 and a9 in your list so i let it go.
Next time i will be looking for CDPs...you mentioned a lot of CDP goodies in the CDP thread.
You should set up a tuner page also ... wala nun sa list ko eh. Also no surplus speakers in the list. Although honestly, i haven't seen any speaker that i like at the pier surplus shops.
Maraming salamat po.
By the way, the PM6 esotec attracted my notice because it was a marantz and the build seemed very good. Thick aluminum front face. Heavy. It is a pity it had problems. I hope somebody who can rebuild it gets it. It powered up, played a track or two and then it heated up very very quickly.

i feel embarassed by your post considering i don't even consider myself an audiophile, more like an audio enthusiast and collector. anyway, kaya malakas ang loob kong magbigay ng audio tips dito, kasi i'm close to 30 years in this hobby.
when i started to work in Makati in 1980, i wasn't satisfied with just a hobby and opened a weekend used hifi trade in Diliman. got additional cash when my Mom died and that expanded my audio inventory at home. it ended in late '80s when my growing kids needed more time and my wife got a 2-year scholarship at UCL in London. well, it would be safe to say that i've used close to 500 audio equipment during those days, from SS to tubes, from entry to upscale models, from US to Brit and Jap brands. also got audio directories from the mid 60s to early '90s (but 2/3 of these directories were eaten by termites early this year).
hope this explains why medyo pakialamero ako with respect to audio equipment info. but to tell you frankly, i'm also learning a lot from members here - even from newbies - as well from those in other forums such as WiredState, Vinyl Engine and AK. i'm definitely not a guru but hope i qualify in giving some hifi tips. thanks for the compliment.

WOW!!! Close to 500 units!!! No wonder you know your audio!!! ;D I believe the compliment is not only for the huge repertoire of audio info in your brain but your willingness to share it....which i believe is more important and admirable.

nanli-liit ako sa posts ninyo Sir Obet and Sir Foo. kasi siguro ganun ako, i'm professionally involved in information and communication. dun ako binabayaran and i enjoy my work, lalo na kung may audio forum na ganito, which serves as pampagana.

i second what the two previous guys said! sir sandawa has been most helpful with his sagely advice and insight. his experience in vintage audio is indispensable.
thank you sir!

teka, walang ganyanan. hindi ninyo alam, salbahe rin ako. you could talk to some fresh graduates i terrorized when i was still working there in Metro Manila. i was onced described by those kids as "berdugo."
pero kapag audio and pinag-uusapan - especially inexpensive surplus amps, CDPs and speakers - palagi akong masaya, sabi nga ni Foo, parang walang talo!

i saw a sony TA-F6B in the marketplace... any comment on this model sirs?
thanks.

Post by sandawa on Aug 10, 2005 8:31:04 GMT 7
i think Sony TA-F6B is a good model considering it came out in 1978 (certified vintage), rated at 100wpc RMS (conservative during those times), almost 27 kgs. in weight and originally sold at $610 in the US. a price of, say, P3K for it would be a steal. up to P5K, if mint condition, is reasonable in my opinion.
its brother, the TA-F7B is a sought-after V-FET model.

Hi Nani, Do you have info on Yamaha B2, one of the best daw.

Louie,
Yamaha B-2 is a much sought-after SS model by audio enthusiasts all over the world. also built in late '70s, it's a V-FET (that's why) and class A @ 100wpc i think.

sir, how about MOS-FETs? I have a Marantz PM-84D MOS-FET... How does it compare with VFETs?
thanks.

MOS-FETs are the usual transistors used by amps before the digital chip. it's the common component in SS amps and is generally blamed for the SS's strained sound, prompting some audiophiles - inlcuding here in RP - to shift back to the old tube technology. MOS-FETs are efficient performers and inexpensive to produce, like the digital chips. as far as i know the VFET was used as a substitute to valve amps in the 70s. its sonic characteristics were more of tube than SS, but it's more efficient and had better specs on paper compared with tube amps. the only problem is that it was a specialized amp technology not shared by the Japs to western manufacturers (no US or European audio firms went into VFET). increasing production cost of VFET plus appreciation of the Japanese yen in early '80s resulted in VFET's demise as a hifi component in the '80s, specifically for Sony and Yamaha (and NEC, i think). Audio Karma has a big group of audio enthusiasts that are VFET fans. the leader of the group is Axel Dahl, Paris-based, who's been communicating with me and Diego. He has also a huge collection of audio literature especially for domestic Japanese models we now refer to here as "surplus amps." Axel also runs The Vintage Knob website: www.thevintageknob.org/

thanks sir for the link and i will read up on that subject.

personally, i think MOS-FET amps could also sound extremely good depending on design and the power it could harness, i.e., the transfomer and power cap quality (and ratings).
of about a dozen amps i have, including a 1979 Yamaha B3 VFET, the clear winner is Sansui Alpha 907, made in 1987 and a MOS-FET. of course, hifi appreciation is subjective and based on personal preference.

Your PM-84D is a good amp model, next to the PM-94 and part of the Quarter A series. mahirap maghanap niyan sa surplus and could be quoted as high as P8K to P10K - upscale price range - by traders here in Davao.
