navinji,

can you tell me how to identify different type of capacitors? i asked my electronic stoe guy for ctr metallized polyester caps(4.7uf and 2.2uf for my infinity 6x9s) he said he didnt have ctr so he gave me some "BC CAPS". MPEA V 5 4.7mf k 250 is written on the cap. the cap has a yellow outside covering with shiny maroon inside.

is it a polyester cap? as i was planning to replace the bipolar electrolytics on my infinity 6x9s.

OT. would like to know if precision caps are available in india. for e.g. a 1% tolerance cap. i need some for my LC meter project. im stuck due to this. accuracy of the meter depends on what tolerance caps i use.

awaiting your reply
cheers

are you sure he said BC caps not Vishay. those markings look like Vishay.

do they look like these
Capacitors - Vishay - Film, Pulse-AC/Precision (Film)
or these
Capacitors - Vishay - Polyester, Radial
or these
MKT 1813 - C-values 470 pF - 22 µF, Voltage 63 - 1000 VDC, Low Profile, AXIAL - Vishay Capacitors
or these
KP 374 - AC and Pulse Polypropylene Film Foil Capacitors KP Radial Epoxy Lacquered Type - Vishay Capacitors

Vishay makes 1% caps too but you have to import them.

Before I was married I used to travel 10-12 times a year so I used to buy my stuff from the US. After getting married and having a family I hardly travel so I ask my BIL in singapore to order stuff for me and keep them at his place. then if I go there i just carry all of it back in one go.

Those caps do look like CTRs but they dont look as well made. I have not heard of BC caps and initially thought you were refering to BC Components (which was merged into Vishay).

navin · 24th August 2007, 23:33

Clip, I can get the components arranged but how do I get these to Jalandar?

sorry I meant CTR. I can even get he 1% caps the next time I go to Sing (at Xmas) but I have no way to get them to Japandar.

Sam Kapasi · 25th August 2007, 12:07

Japandar is a place between Tokyo and Punjab isn't it?

Sam does not have to look beyond me. Most of my life I suffered from 2 maladies A.D.D and Dyslexia. The A.D.D improved after I got involved in Tennie (Volvo Tennis League) and Music (3 chord metaladies) but the Dyslexia is the same hence the typos keep surfacing.

Navin/Sam/Ajay - What do you guys think of current Nakamichi speakers? A prominent dealer in Delhi (Auto Marc aka Sanjay, LBM's dear friend!) is hard selling them.

I have no idea about how good or bad they are.

Nakamichi has lot much of it's sheen. I did get to listen to a pair of components (in fact I compared them to the Infintiy 6010 that are in my wife's car) and I did not like them enough. They looked well made and the bass was nice but the tweeter left much to be desired. For that matter I had already modified the 6010 XO so I dont know if I could have made the Naks sound nicer by doing the same.

What does LBM think (I presume he has heard them)?

A lot of Nakamichi has come in through some grey route: subs, comps, amps etc. Not heard any of it. Will let you know when I do. For a grey product it isn't exactly very cheap.
