Yes, a Sony STR-V6 Bluetooth connection needs no soldering. Best path: a Bluetooth receiver with RCA output into the AUX input (150 mV line level, with DIN at the same figure, per the manual transcription). If AUX is taken, use a Tape loop. Rated 115 W/ch into 8 ohms, the STR-V6 documented here is the 1978 V-series receiver the transcription describes, 21.9 kg of it.

Where to connect
AUX input
RecommendedOne always-active line input at 150 mV, with DIN at the same figure, per the manual transcription. Any line-level Bluetooth receiver with RCA output sits in cleanly; the level check earns its minute on a 150 mV input.
Tape monitor loops
Good alternativeThe tape chain carries record outputs at 150 mV (line) and 40 mV (DIN). Feed a loop's play jacks, select the tape position to listen, and switch the monitor back off for the other sources.
Phono input
Not for line-levelThe MM phono stage expects a cartridge's 2.5 mV. Line-level Bluetooth output would overload it, and the turntable would lose its input.
Set up in three steps
- Pick AUX
Keep the tape loops free for recorders; AUX is the natural Bluetooth home.
- Connect and power
Bluetooth receiver RCA out to AUX, USB power attached, pair once with your phone.
- Level check
Volume low, select AUX, then raise. Fixed/line output on the adapter if it offers the option.
Quirks and notes
- One documented generation (verified): the transcription dates this V6 to 1978 with the STR-V5 and STR-V7 as listed siblings, and targeted searches for an earlier V-series receiver of the same name returned nothing supportable. This page documents the 1978 set and carries the reference-site absences as part of that record.
- 115 honest watts in 1978 (verified): the transcription's 115 W/ch into 8 ohms at 0.07% distortion, with a resale listing's "2 × 115 WRMS monster receiver" phrasing in agreement, places the V6 in this archive's 110-plus-watt shelf beside the Sansui 9090 and G-8000.
- A 100 dB line figure (verified): the transcription's 100 dB line signal-to-noise is among the best documented in this archive's Sony set, one more datum that arrives because the source is the manual transcription rather than a listing.
What you need
- Bluetooth receiver with RCA output, LDAC or aptX HD preferred
- 0.5–1 m RCA cable
- USB power for the receiver
FAQ
Plug a Bluetooth receiver with RCA output into the AUX input and select AUX. If AUX is occupied, use a Tape input through the tape monitor. No internal modification is needed.
Per the manual transcription: AUX/line 150 mV, DIN 150 mV, and MM phono 2.5 mV, with signal-to-noise of 100 dB on line and 75 dB on phono. Outputs run 150 mV (line) and 40 mV (DIN), into speakers of 4 to 16 ohms.
The manual transcription rates 115 W per channel into 8 ohms with a frequency response of 5 Hz to 50 kHz at 0.07% distortion and a damping factor of 40. A resale listing quoting 2 × 115 W RMS for a "monster receiver" agrees with that figure.
The documented record here covers a single generation: the 1978 receiver the manual transcription describes, with the STR-V5 and STR-V7 as listed siblings. A used-unit buyer should still confirm features on the set itself, since this site's two reference encyclopedias carry no V6 entry at all.
